Salesforce Performance and Scale Test FAQs

Performance Tests at 120 RPS or Below

How to Request a Performance Test at 120 RPS or Below

To request a performance test at 120 RPS or below, contact Support via the Salesforce Help site. Submit an LAP request for approval at least one week before the testing date. Requests without advance notice are denied unless categorized as urgent.
Your test plan must include:

• A copy of the test plan that you created in Scale Test (image shown for example only).

• Test start date and time
• Test end date and time
• The Org ID of the sandbox where the test occurs (scale tests are only permitted in sandboxes)
• Contact information for the person conducting the test (name, phone, email)
• The business case or scenario being tested (for example: holiday shopping event, new website launch)
• The business justification for testing

How to Run a Scale Test Above 120 RPS

Changes and customizations to your Salesforce implementation can impact performance. For testing above 120 RPS, use the Salesforce Scale Test product.
To get started:

1. Read Measure Performance for Your Salesforce Org, then generate your test plan and schedule a testing window with Scale Test. 

2. Contact your customer success representative or account executive for access. In Setup, search for Scale Test in the Quick Find box.

Scale Test is a paid add-on for full sandbox users. It validates a Salesforce implementation's ability to handle production-level traffic using metrics such as RPS, Experienced Page Time (EPT), and server-side traffic.

How to Create a Scale Test Plan

Before testing, review Salesforce Developer Limits. Exceeding these limits can result in throttling.
Steps to create your test plan:

1. Identify the test scenarios and their success criteria.
2. Visit the Test Plan Creation page in Scale Test to build a trial run based on production peak-hour usage. Greenfield customers and customers about to go live should design their own test plans using the RPS estimator.
3. Run a baseline test with 50 users for a minimum of 30 minutes in a sandbox. Tests with 50 users or fewer usually do not require case approvals.
4. Use the Trial Accuracy Checker to simulate production peak-hour traffic in a sandbox trial run.
5. Use the RPS Estimator in Scale Test to calculate the expected peak load for inbound requests and API calls.

Frequently Asked Questions

What is the difference between a Performance Test and Scale Test?

A Performance Test is for testing at 120 RPS or below and is requested via the LAP process through Salesforce Support. Scale Test is for testing above 120 RPS and requires a paid add-on and coordination through your Account Executive.

My test was approved. Does that mean Salesforce considers my scripts valid?

Not necessarily. Salesforce Support does not validate testing methodology, debug testing scripts for errors, or confirm that scripts accurately reflect real-world production scenarios.
Support recommends for all test execution frameworks:

• No hard-coded locations to external files in scripts
• Parameterized URLs, usernames, and passwords
• Disabled single sign-on and no IP range restrictions for user profiles
• Five-second think time between requests

Can I run a scale test without prior approval?

No. All tests must be pre-approved. Unapproved testing is subject to throttling or blocking. Pre-approval allows Salesforce Support to schedule Site Reliability (SR) and Customer Centric Engineering (CCE) resources and to monitor the test. Even approved testing can be throttled if it degrades performance on the instance.

Can I get server logs for my scale testing?

Salesforce does not provide overall metrics or server logs for the testing period. For specific requests — such as CPU time for a particular process or details to troubleshoot an error — Support can sometimes extract a limited set of server log data. Work with your support agent.
Proactive Monitoring (PRoM) works alongside Scale Center as part of Salesforce's scalability suite. Use Scale Center for performance monitoring, analysis, and on-demand Lightning Experience Insights.
