Why Is NetSuite Slow? 47-Point NetSuite Performance Audit Guide (2026)

You went live. The consultants left. And now NetSuite is slower than it was six months ago.

Page loads that used to take three seconds now stretch to eight. Saved searches time out. The script execution log is full of governance errors. Users are asking if "the server is down again."

No one told you this would happen. But here you are.

The truth is simple: NetSuite doesn't slow down on its own. It slows down because of what accumulates after implementation. 

That’s what we call operational drift. And it costs you in ways that don't show up on an invoice. 

Industry data shows ERP performance issues can cost large organizations up to $9,000 per minute in downtime. 

But the hidden costs hurt more: abandoned adoption, repeated training, lost trust in the numbers, decisions delayed because the system "isn't working right."

A NetSuite Performance Audit exists to reverse this. 

Our guide covers 47 specific checkpoints across nine categories: infrastructure, data, scripts, searches, workflows, forms, integrations, testing, and security. 

Each one addresses a proven bottleneck we've seen across dozens of post-implementation environments.

You'll know what to look for. Where to find it. How to fix it. And when to call it done.
‍

What Are the Warning Signs Your NetSuite Needs a Performance Audit?

Performance problems don't announce themselves with error messages. They creep in slowly, compounding over weeks and months until "slow" becomes normal.

Here's what to watch for. If you see three or more of these patterns, you're past due.

1. Page loads consistently over five seconds. Double-click the NetSuite logo to see the Performance Details window. If "Server Script Time" dominates, you have script bloat. If "Client Time" or "Network Time" dominates, the issue is browser-side or infrastructure.
2. Saved searches that time out regularly. Especially searches used in dashboards or reports. If users are building workarounds in Excel because "the search doesn't finish," you have query optimization problems.
3. Governance limit errors in script logs. Go to Customization > Scripting > Script Execution Log. Filter for your busiest scripts. If you see "SSS_USAGE_LIMIT_EXCEEDED" repeatedly, your code is inefficient. Probably looping record.load calls or running unfiltered searches.
4. Queue backlogs in scheduled scripts. Check your scheduled script deployment records. If you see "Pending" status for more than a few minutes during off-peak hours, your processor queues are saturated. Either you need SuiteCloud Plus or your scripts need better timing.
5. Users say "NetSuite is slow today" multiple times per week. This isn't a network issue. It's systemic. Performance degradation that users notice means the cumulative weight of customizations has crossed a threshold.
6. Month-end close takes longer every quarter. If close went from three days to six days over the past year, data volume is outpacing your system's ability to process it. Usually a combination of unarchived transactions and unoptimized revenue recognition or consolidation workflows.
7. Integration failures or timeout errors. Check your middleware logs (Celigo, Boomi, whatever you use). If API calls are hitting concurrency limits or returning 500 errors, your web services layer is overloaded.

One healthcare client came to us after users started complaining that invoice pages took 12 seconds to load. 

Performance Details showed 9 of those 12 seconds were Server Script Time. We found 12 workflows created during implementation that were still active. None of them were needed anymore. 

The business had changed. The workflows hadn't. We turned them off. 

Load time dropped to 4 seconds. No code changes. No infrastructure upgrades. Just removing what shouldn't have been there.

That's what NetSuite Performance Audits catch. The things hiding in plain sight because no one knew to look.
‍

When Should You Run a NetSuite Performance Audit?

You can't audit once and call it done. Businesses grow. NetSuite evolves. Customizations multiply. What performed well at 10,000 transactions per month breaks at 50,000.

Here's the schedule that keeps systems healthy.

One BPO client scheduled quarterly audits after their initial optimization. Each audit surfaced three to five new inefficiencies introduced by business growth. 

Catch them early, fix them fast. That's how you prevent regression.

Cost matters here. Skipping audits doesn't save money. Technical debt compounds at roughly 15-20% per quarter. 

A problem that takes two hours to fix today takes eight hours to fix in six months. Because by then, other customizations depend on the broken pattern. And users have built workarounds that now "need" to stay.

Align audits with your fiscal calendar. Tie them to quarterly close or annual planning cycles. Make them predictable. Assign ownership to your NetSuite admin or a managed services partner. 

The worst time to discover performance problems is during year-end close when the CFO needs numbers yesterday.
‍

What Tools Should You Use for NetSuite Performance Monitoring?

You can't optimize what you can't measure. NetSuite gives you native tools that most admins never use. 

Combine those with a few external options and you have complete visibility.
‍

1. Application Performance Management (APM)

This is Oracle's dashboard for real-time system health. 

You'll find it under Setup > Company > Enable Features > SuiteCloud > Application Performance Management. Turn it on if it's not already.

APM shows script execution times, governance usage, queue depths, and page load breakdowns. You can drill into specific scripts and see which ones consume disproportionate resources. 

If a User Event script averages 8 seconds per execution, APM will show you. That's your starting point for optimization.
‍

2. Performance Details window

Double-click the NetSuite logo on any page. You'll get a pop-up showing how long the page took to load, broken into categories: Server Script Time, Server Processing Time, Client Time, Network Time.

• If Server Script Time is high (over 50% of total), you have script inefficiency. 
• If Client Time dominates, you have browser-side problems (heavy client scripts, too many portlets). 
• If Network Time is high, check your firewall rules and WAN latency. Make sure *.app.netsuite.com is accessible through your CDN.
  ‍

3. Script Execution Log

1. Go to Customization > Scripting > Script Execution Log. 
2. Filter by date range, script type, or user role. 
3. Look for executions with high usage units (over 1,000 for User Events, over 5,000 for scheduled scripts). 
4. Look for errors, especially "SSS_USAGE_LIMIT_EXCEEDED."

This log tells you which scripts are firing too often, taking too long, or failing silently. Export it to CSV and sort by execution time. 

The top ten scripts are usually where 80% of your performance problems live.
‍

4. System Notes audit

System Notes track every change to a record. They're useful for compliance. They're also a performance killer if you're not careful. 

Go to a high-volume transaction type (Sales Order, Invoice) and open the System Information subtab. If you see thousands of system notes per record, you're storing unnecessary audit trails.

1. Check which fields have "Track Changes" enabled. 
2. Turn it off for low-value fields like "Memo" or "Last Modified Date." 
3. Keep it on for fields that matter (Amount, Status, Approval).
   ‍

5. Real User Monitoring (RUM) tools

If you want to track page load times from actual user sessions, tools like New Relic Browser or Dynatrace work. They measure time to first byte, full page render, and JavaScript execution time. 

(Not essential, but helpful if you're troubleshooting client-side performance and need more granularity than Performance Details provides.)
‍

6. Integration middleware logs

If you use Celigo, Boomi, or Dell Boomi, check their dashboards for throughput metrics. 

• Look for API calls with response times over three seconds. 
• Look for retry patterns or authentication failures. 

Most middleware tools will show you which NetSuite endpoints are slowest.
‍

7. Third-party BI tool query logs

If your users run Tableau or Power BI dashboards connected to NetSuite via ODBC, check the query logs. Live queries ("Direct SQL") can tax the database. 

Switch to scheduled exports or use SuiteAnalytics Connect for better performance.

One distribution client was running 23 Tableau dashboards with live NetSuite connections. Each query pulled unfiltered transaction history. 

We moved them to a nightly CSV export to a data warehouse. 

Dashboard refresh times went from 45 seconds to 3 seconds. NetSuite stopped seeing random slowdowns during business hours.

• Set up baseline metrics before you start optimizing. 
• Run APM for a week. 
• Capture Performance Details on your ten most-used pages. 
• Export script logs for your busiest day of the month.

You need the "before" snapshot to prove the "after" improvements.
‍

How to Use This 47-Point Checklist Effectively

This isn't a one-day exercise. Effective audits take four to six weeks depending on system complexity. Here's how to sequence the work.

• Week 1: Discovery. Run APM if it's not already running. Capture Performance Details on slow pages. Export script execution logs for the past 30 days. Pull a list of all saved searches, workflows, and scheduled scripts. Count transaction records by type (Sales Orders, Invoices, Bills, Inventory Adjustments). You're building the baseline.
• Week 2: Infrastructure, data, scripts. Work through checkpoints 1-25. Audit SuiteCloud Plus licensing. Check data volumes and archiving status. Review every custom script for inefficient patterns. This is where you'll find the biggest wins.
• Week 3: Searches, workflows, forms. Cover checkpoints 26-41. Optimize saved searches. Audit workflows for redundancy. Trim custom forms. Fix client scripts. These are high-visibility improvements. Users will notice pages loading faster.
• Week 4: Integrations and testing. Finish checkpoints 42-47. Profile RESTlets and Suitelets. Check CSV import settings. Test your changes in Sandbox or Release Preview before deploying to production.
• Week 5: Remediation roadmap. Prioritize findings by impact versus effort. Assign ownership. Create a phased rollout plan. Communicate changes to stakeholders.

Prioritize using this framework:

Never skip these:

One real estate client had no documentation from their previous consultant. We spent the first week just mapping what was configured and why. Built a system review document showing current setup, identified issues, and proposed fixes. 

That document became their single source of truth. When their finance lead left six months later, the new hire didn't have to reverse-engineer everything.
‍

What Should a Comprehensive NetSuite Performance Audit Cover?

Every performance problem falls into one of eight categories. Address all eight or you're guessing.
‍

Infrastructure, Governance, and Application Performance Management (7 points)

Even perfect customizations fail on misconfigured infrastructure. Start here to rule out foundational issues.

1. SuiteCloud Plus licensing and concurrency limits

• Check: Setup > Company > SuiteCloud Plus
• What to verify: Concurrency limits match your workload
• Benchmarks: Standard tier = 5 threads, Premium = 15 threads
• Red flag: "Concurrent request limit exceeded" errors or queue backlogs
• Fix: Add SuiteCloud Plus licenses for scheduled scripts, CSV imports, web services

2. APM dashboard deployment

• Check: Setup > Company > Enable Features > SuiteCloud > Application Performance Management
• What to verify: APM is enabled and actively monitored
• What it shows: Script execution times, governance usage, queue depths in real time
• Why it matters: You can't fix what you can't see

3. Performance Details analysis on slow pages

• Check: Double-click NetSuite logo on any page
• What to verify: Which time category dominates (Server Script, Client, Network)
• Server Script Time >50%: Inefficient User Event scripts
• Client Time >50%: Heavy client scripts or too many portlets
• Network Time >50%: Firewall rules, WAN latency, CDN accessibility issues

4. Script Execution Log review

• Check: Customization > Scripting > Script Execution Log
• Export: Last 30 days, sort by execution time
• Red flags: User Events >5s, Suitelets >10s, Scheduled Scripts >5min, error rate >5%
• Quick win: Top 10 slowest scripts = 80% of your performance problems

5. Service tier verification and network configuration

• Check: Confirm current tier (Standard, Premium, Enterprise) matches transaction volume
• Validate: *.app.netsuite.com accessible through corporate network
• Red flag: Standard tier with 50+ concurrent users and 100K+ transactions/month
• Also check: Proxy servers, firewall rules throttling connections

6. Governance threshold monitoring

• Set alerts: Scripts approaching 10K usage units
• Track: Map/Reduce stage failures
• Don't: Buy more capacity and hope it fixes itself
• Do: Optimize code first, then add capacity if needed

7. System Notes audit trail and multi-subsidiary overhead

• Check: Setup > Company > General Preferences > System Notes
• What to verify: Track Changes enabled only on compliance-critical fields
• Red flag: 50+ fields tracked per record type = unnecessary bloat
• Also audit: Cross-subsidiary permissions (roles with broad "View All" slow record loads)
  ‍

Data Volume, Architecture, and Indexing Strategy (8 points)

Data is fuel. Too much unarchived, unindexed data becomes sludge.

8. Transaction volume quantification

• Check: Reports > Saved Searches > New
• Count by type: Sales Orders, Invoices, Bills, Inventory Adjustments, custom records
• Red flag: Any table >1M rows
• Action trigger: Archive or purge old data

9. Data archiving strategy

• Verify: Closed-period transactions >3-5 years old are archived off-platform
• Method: Export to CSV or third-party archiving SuiteApp
• Goal: Keep live database lean
• Case study: Telecom client archived 2.3M rows = 45% faster searches, month-end close from 6 days to 3.5 days

10. Custom field proliferation audit

• List: All custom fields via Customization > Lists, Records, & Fields
• Mark: Which are used in searches, workflows, reports
• Red flag: Field not referenced in 12 months + usage <5%
• Fix: Deactivate or delete unused fields

11. Duplicate record cleanup

• Run searches: Duplicate Customers, Items, Vendors
• Look for: Near-identical names, addresses, emails
• Fix: Merge or delete
• Why: Dirty data inflates record counts, complicates reporting

12. Custom record indexing

• Check: Customization > Lists, Records, & Fields
• Mark "Indexed": Custom fields frequently used in saved search filters
• Examples: Status fields, custom type fields
• Why: Indexes speed up queries; without them, NetSuite scans entire table

13. System Notes retention policy

• Check: Setup > Company > General Preferences > System Notes
• Set purge policy: Logs beyond compliance window (usually 7 years)
• Disable: Audit trails on low-value fields
• Why: System Notes are heavy; don't store more than legally required

14. Record locking pattern analysis

• Check for: Transactions causing contention (inventory adjustments, bin transfers, item receipts)
• Red flag: Record locks during peak business hours
• Fix: Schedule heavy batch jobs 2am-6am PST (NetSuite's low-traffic window)

15. Multi-currency overhead and data quality

• Check: Exchange rates cached, not recalculated on-demand
• Audit: Currency revaluation jobs (reschedule if running during business hours)
• Flag: Orphaned child records, mismatched currencies, inconsistent naming conventions
• Also verify: Storage quota vs. usage (plan expansion before hitting 80%)
  ‍

SuiteScript Performance and Custom Code Optimization (10 points)

Custom code is where performance lives or dies.

16. SuiteScript version audit and deployment cleanup

• List: Every script, note version (1.0, 2.0, 2.1)
• Migrate: Scripts on 1.0 to 2.1 (Oracle-confirmed performance gains)
• Check: Customization > Scripting > Scripts > each deployment
• Fix: Set unused deployments to "Testing" or "Not Deployed"

17. Execution context filtering

• Check: "Context" settings on each script deployment
• Rule: User Event scripts should only fire on necessary actions
• Example: If script only needs "Edit," remove "View," "Create," "Copy," "Delete"
• Why: Fewer executions = less overhead

18. N/query versus saved search migration

• Replace: Heavy saved searches in scripts with N/query or SuiteQL
• Governance savings: 40-60% compared to search.create + record.load loops
• Example: Script looping 500 invoices with record.load = 5,000 units. One N/query = 500 units.

19. record.submitFields versus load/save pattern

• Audit: Scripts using record.load, modify field, record.save
• Replace with: record.submitFields
• Benefits: Updates specific fields without instantiating entire record, lower governance, no record locking

20. search.lookupFields for single-field retrieval

• Use when: You only need 1-2 field values from a record
• Don't: Load entire record with record.load
• Why: No overhead from sublists, custom fields, related records

21. runPaged batching for large result sets

• Replace: Unbounded searches with search.runPaged
• How it works: Processes results in chunks (1,000 rows/page)
• Benefits: Prevents memory errors, plays nicely with governance limits

22. Map/Reduce chunking strategy

• Rule: Return search object from getInputData, not array of IDs
• Why: Oracle runs searches with extended time limits; arrays risk timeouts
• Governance limits: Map stage = 1,000 units, Reduce stage = 5,000 units

23. N/cache for static data lookup

• Cache: Frequently-accessed data (tax codes, GL accounts, exchange rates)
• Avoid: Repeated database calls for data that doesn't change intraday
• Governance savings: Add up fast across high-volume operations

24. Client script versus User Event placement

• Move logic: From client-side (pageInit, fieldChanged) to server-side (afterSubmit)
• Why: Client scripts slow browser; User Events run on server with more processing power
• Result: Faster page loads for users

25. External API batching and File Cabinet optimization

• Don't: Make synchronous web service calls on every save
• Do: Queue data, process asynchronously via scheduled script or Map/Reduce
• File Cabinet: Minimize runtime file loads; pre-process offline or cache in memory
• Case study: Healthcare client eliminated 500 manual entries, 8 hours → 45 minutes, 100% automation
  ‍

Saved Searches, Reports, and Analytics Performance (6 points)

Saved searches are NetSuite's most abused feature.

26. "Contains" operator elimination

• Audit: Every saved search in dashboards or reports
• Replace: "Contains" with "starts with" or "has keywords"
• Why: "Contains" forces full table scan; "starts with" uses indexes (10x speed difference)

27. Date range enforcement

• Add: Mandatory date filters (last 12 months or current fiscal year)
• Red flag: Searches pulling 5 years of transaction history
• Why: Major source of timeouts

28. Formula field and result column trimming

• Count: Result columns using custom formulas
• Red flag: Searches with >15 columns
• Remove: Unused columns, especially System Note fields
• Alternative: Store calculated values in custom field (update on save) instead of formula

29. Scheduled search inventory

• Check: Lists > Saved Searches > All Saved Searches > filter by schedule
• Red flag: Searches running hourly/nightly that nobody remembers requesting
• Case study: Client had 47 scheduled searches, 23 orphaned = 18% nightly capacity freed

30. SuiteAnalytics Workbooks migration

• Use for: Complex reporting needs (10+ table joins)
• Why: Workbooks handle large joins more efficiently than saved searches
• When: Users building multi-table join searches

31. Summary function optimization

• Use: Grouping/aggregation (SUM, COUNT, AVG) instead of raw result sets
• Example: 500 grouped rows faster than 50,000 raw rows aggregated in Excel
  ‍

Workflows, Automation, and Batch Processing (5 points)

Workflows automate processes or automate slowdowns.

32. Workflow redundancy analysis

• List: All active workflows (Customization > Workflow > Workflows)
• Look for: Overlapping logic (3 workflows all firing on Sales Order save)
• Fix: Consolidate
• Why: Every workflow adds execution time; redundant workflows multiply it

33. Recursive trigger prevention

• Check for: Workflows that re-trigger themselves
• Fix: Add state conditions (custom checkbox "Workflow Processed = T")
• Condition: Only run if "Workflow Processed = F"

34. Scheduled script timing strategy

• Audit: When scheduled scripts run
• Stagger: Heavy jobs across 2am-6am PST window (30min intervals)
• Don't: Start 5 batch scripts at 2:00am
• Why: Avoid processor contention

35. Processor queue allocation

• Check: Setup > Company > SuiteCloud Plus Settings
• Verify: Deployments use multiple queues (if SuiteCloud Plus enabled)
• Red flag: "Not Scheduled" (API-triggered) scripts saturating pools

36. Nightly batch sequencing

• Map: Dependencies between jobs
• Example: Invoicing 2-3am → Revenue recognition 3:30am → Dunning 5am
• Don't: Overlap jobs writing to same records
• Case study: Real estate client automated commissions via Map/Reduce, 10K transactions/month unattended
  ‍

Forms, UI, and Client-Side Performance (5 points)

Users blame "NetSuite" when forms are slow. Usually it's form bloat.

37. Sublist delay loading enforcement

• Check: Home > Set Preferences > General > Optimizing NetSuite
• Enable: "Delay Loading of Sublists"
• What it does: Subtabs load on-click, not page init
• Impact: Massive on transaction forms with many line items

38. Custom form field audit

• Audit: Every custom form, count fields
• Remove: Unused fields
• Create: Role-specific forms ("quick entry" for high-volume users, "detailed" for managers)

39. Client script weight reduction

• Profile: pageInit and fieldChanged functions
• Red flag: Looping through line items or making multiple search calls
• Fix: Move calculations to User Events (server-side)

40. List segment sizing

• Check: Home > Set Preferences > General > Optimizing NetSuite
• Set: List pages to 50 rows/page
• Why: Prevents very long lists from auto-loading

41. Form field sourcing optimization

• Check: Fields set to "Source From"
• Red flag: Calculated sourcing (pulls value on every page load)
• Fix: Switch to "Store Value" sourcing (store once at save time)
  ‍

Integrations, APIs, and External Systems (4 points)

Integrations extend reach. Poorly designed APIs become sinkholes.

42. RESTlet and Suitelet profiling

• Use APM: Identify slow API endpoints
• Red flag: RESTlet >3s response time
• Check code: Unfiltered searches? Record loops?
• Fix: Refactor or cache results

43. CSV import multi-threading

• Check: Setup > Company > General Preferences > CSV Imports
• Enable: Maximum threads (more with SuiteCloud Plus)
• Strategy: Split large files, run multiple imports concurrently during off-peak hours

44. API concurrency and third-party BI tool impact

• Monitor: SuiteTalk (SOAP/REST) call volumes
• Red flag: "Concurrent request limit exceeded"
• Fix: Better batching (don't make one API call per record)
• BI tools: Switch Tableau/Power BI from live queries to scheduled exports

45. SuiteCommerce performance and integration error patterns

• Profile: Storefront page loads, catalog searches, cart calculations
• Optimize: Images, lazy-load thumbnails, cache catalog data
• Review: Webhook logs, middleware dashboards (Celigo, Boomi)
• Flag: Recurring timeout/authentication failures
  ‍

Testing, Validation, and Release Management (2 points)

Production isn't a test environment.

46. Sandbox load testing and staging data strategy

• If you have Sandbox: Replicate production data volume (don't test with 100 records if prod has 100K)
• Staging data: Maintain representative dataset (10% of transactions, anonymized customers, full item catalog)
• No Sandbox? Use Release Preview (available 4-6 weeks before releases)

47. Release regression testing and performance baseline

• After each NetSuite release: Validate KPIs (page loads, search times, script execution)
• Red flag: Performance degrades >10%
• Document: Current-state metrics before optimizing (need "before" snapshot for "after" proof)
• Case study: BPO client used Release Preview for testing, saved $300-1,000, achieved 80% faster approvals
  ‍

How Do You Measure NetSuite Performance Success?

"Faster" is subjective. Define success with measurable KPIs that stakeholders can track.

Set targets before you optimize. Then measure again 30, 60, and 90 days post-remediation. Here's what good looks like.

How to track: 

• Use Performance Details (double-click NetSuite logo) for page loads. 
• Pull Script Execution Log for script times. 
• Time your top 20 saved searches manually.
• Profile RESTlets with APM. 
• Track close duration every month.

Share with leadership:

• Create a simple dashboard.
• Update monthly. 

Performance isn't invisible anymore. It's measurable, predictable, and improvable.

One telecom client reduced manual VAT entry errors from 15% per month to zero by automating tax recognition. Compliance risk eliminated. Audit prep time cut 70%. 

The ROI case built itself.
‍

What Are the Most Common NetSuite Performance Bottlenecks?

Across hundreds of audits, the same culprits appear. Recognize these patterns to prioritize your fixes.

1. Unarchived transaction history. Multi-year datasets slowing searches and reports. Five years of closed transactions = every search evaluates millions of unnecessary rows.
2. Inefficient saved searches. "Contains" operators, unlimited date ranges, excessive formula fields. One bad search in a dashboard slows the entire system.
3. Synchronous script patterns. record.load loops, real-time API calls in User Events. Loading 200 records one at a time when one query could get all 200.
4. Obsolete workflows and scripts. Legacy automations firing unnecessarily. The business changed. The workflows didn't.
5. Insufficient SuiteCloud Plus capacity. Queue saturation during batch windows. Scheduled scripts waiting hours for a free processor.
6. Client script bloat. Heavy pageInit logic. Looping through 500 line items to calculate a total. The user waits 10 seconds.
7. Duplicate and dirty data. Inflated record counts. Searches returning 10,000 results when 500 are legitimate and 9,500 are garbage.
8. Integration middleware inefficiencies. Single-threaded API calls. One integration calling NetSuite 50,000 times per day when batching could reduce it to 500.
9. Missing indexes on custom fields. Frequently-filtered fields not marked for indexing. Every search scans the whole table.
10. Form overdesign. Forms with 100+ fields, unnecessary sublists, too many portlets. The user doesn't need 80% of what's on the screen.

Fix the top three bottlenecks and you'll see 60% improvement. That's the 80/20 rule. Most performance problems cluster in a few areas. 

Find them. Fix them. Move on.
‍

How Often Should You Audit NetSuite Performance?

One audit isn't enough. Operational drift is constant. Audits must be too.

• Annual comprehensive audit. Full 47-point checklist. All categories. Deep dive. Budget 4 to 6 weeks. Assign a dedicated project team. This is your reset.
• Quarterly focused audits. Scripts, workflows, saved searches. These are high-change areas. Business processes evolve. Customizations multiply. Quarterly checks catch new inefficiencies before they compound.
• Post-major-change audits. M&A activity, new integrations, subsidiary additions, product line launches. Any structural change warrants a focused audit. Don't wait for complaints.
• Trigger-based audits. Five or more user complaints per week. Month-end delays. Governance error spikes. Integration failures. These aren't isolated incidents. They're symptoms of accumulated debt.
  ‍

What Happens After You Run the Audit?

Findings without action are expensive documentation. Here's how to turn audit results into improvement.

One healthcare client documented every change in a system review. When their admin left six months later, the new hire didn't have to reverse-engineer everything. The documentation was the handoff.

Don't declare victory and walk away. Performance audits are cyclical. 

Audit, remediate, monitor, re-audit. That's the rhythm. Businesses grow. NetSuite evolves. Customizations accumulate. 

The work never ends. But it gets easier when it's routine.
‍

Ready to Stop Fighting Your ERP?

This 47-point checklist gives you the framework. But frameworks don't execute themselves.

You need someone who knows where to look. Someone who understands that performance isn't just about speed. 

It's about continuity. It's about reliability. It's about making sure that when your finance team opens NetSuite at 8am on day one of close, the system doesn't fight them.

If your NetSuite environment is showing warning signs, we can help. 

Stockton10 specializes in post-implementation support for companies that need their NetSuite to work predictably, not perfectly. We run comprehensive performance audits, identify what's causing slowdowns, and implement fixes that actually stick. 

Schedule a performance assessment and we'll show you exactly where your system is bleeding time, governance units, and user trust.
‍

Frequently Asked Questions

Why is NetSuite slow and how to fix it?

Slowness stems from unarchived data, inefficient scripts, unoptimized searches, or infrastructure limits. A 47-point audit identifies root causes. Common fixes: archive old transactions, upgrade to SuiteScript 2.1, replace "contains" operators with "starts with," add SuiteCloud Plus capacity.
‍

How to use APM for SuiteScript bottlenecks?

Enable Application Performance Management under Setup > Company > Enable Features > SuiteCloud. APM dashboards show script execution times, governance usage, and queue depths in real time. Drill into scripts exceeding 5 seconds (User Events) or 10 seconds (Suitelets) for refactoring.
‍

Should I switch to N/query for complex joins?

Yes, especially for scripts processing over 1,000 records. N/query and SuiteQL return lightweight result sets without instantiating record objects. Governance savings: 40 to 60% compared to saved searches plus record.load loops.
‍

How to prevent record locking and timeouts?

Use record.submitFields instead of load/save to update specific fields without locking entire records. Schedule batch jobs (inventory adjustments, bin transfers) during off-peak hours (2am to 6am PST). Implement optimistic locking patterns in Map/Reduce.
‍

How many lines is too many for a transaction?

Transactions with over 500 line items risk performance degradation. Consider batch processing (combine multiple POs into fewer transactions) or use Map/Reduce to process lines asynchronously. Audit sublist loading preferences to delay non-critical tabs.
‍

What's the difference between performance audits and health checks?

Health checks are lightweight assessments: basic config, user permissions, data integrity. Performance audits are technical deep dives: APM analysis, script profiling, query optimization, infrastructure tuning. Audits take 4 to 6 weeks. Health checks take 1 to 2 weeks.
‍

How much does poor NetSuite performance cost?

Industry data estimates ERP downtime costs $5,000 to $9,000 per minute for large enterprises. Hidden costs include manual workarounds (2 to 5 hours per week per user), delayed financial closes (opportunity cost), abandoned adoption (training waste), and lost revenue (order processing delays).
‍

Can I run performance audits without a Sandbox?

Yes. Use Release Preview environments (available 4 to 6 weeks before major NetSuite releases). Test optimizations there before deploying to production. For ongoing testing, invest in Sandbox ($300 to $1,000 per month) to replicate production load safely.
