Measure Performance for Your Salesforce Org
Set up your test org and test client, and accurately measure performance.
A good testing strategy evaluates both performance and scalability. Performance refers to the speed and effectiveness of a system under a given workload within a given time frame. Scalability is the ability of a system to meet its response time or throughput objectives under increasing application and system processing demands. Make your implementation performant and scalable.

Plan Your Performance Test and Identify Key Personas
Create an accurate sandbox org and plan your test using key personas.
We recommend using a sandbox that is a full copy of your production org. Make sure that your sandbox’s data model is similar to production.
- Draw a system diagram to visualize current and future features, systems, and users that involve Salesforce. For each part of the system, estimate peak load levels, average load levels, and feature use. Consider user arrival rates, login rates, which pages are viewed, and page views per session. If available, any existing site data as a starting point.
- Calculate the throughput of your system in Requests per Second (RPS). RPS combines inbound XMLHttpRequests (XHRs) and API calls, both of which are supported by Event Monitoring. For help with accessing these metrics, see Using Event Monitoring.
- Estimate the size and shape of your data, including the number of accounts, users, feeds, groups, and other objects.
- In your sandbox org, include any complex relationships between your objects, role hierarchies, and sharing rules.
After your sandbox org is set up, identify the key personas for your org and plan your tests around their page flows. Different personas have different data volumes and data visibility. Performance for a persona with a wide view of your org’s data, like the VP of Sales, can be different from users with more specialized roles. Use your key personas to build a site map and identify likely page flows for each persona.
Set Up and Run Performance Tests
Create tests that evaluate your networks, key personas, and data loading.
Before measuring your org’s performance, measure your browser’s octane score and network latency using the same hardware and network conditions as your users. Resolve any performance issues before testing your org.
For each test, define the scope of your investigation, what components are involved in the test, and what metrics you want to measure. Run your performance test multiple times to eliminate variance. Run your tests at regular intervals, and take note of any changes in response times and throughput. Performance testing is an iterative process. Finding and solving issues uncovered by your tests can uncover more issues.
Salesforce measures performance in Experienced Page Time (EPT). You can measure EPT in four ways.
Add an EPT counter to the header of your app
To add an EPT counter to the header of your app, use Lightning Component Debug Mode, or
append ?eptVisible=1 to your URL.
Lightning Component Debug Mode slows performance because it doesn’t minify code. Using
?eptVisible=1 has a smaller impact on
performance.
Use the Lightning Usage App to view page and browser performance
To measure EPT with the Lightning Usage App, select a tab in the Activity or Usage section on the left side of the page. You can view EPT by the browser used, or by page. Because the Lightning Usage App aggregates performance metrics, using the EPT counter can be better for measuring specific pages.
Build a custom report using Lightning Usage App objects
To measure EPT with custom reports in the Lightning Usage App, create a report type using a Lightning Usage App object. After you create the report type, build the report using Report Builder. The Lightning Usage App objects aren’t available in your sandbox org and include:
- LightningUsageByAppTypeMetrics
- LightningUsageByBrowserMetrics
- LightningUsageByPageMetrics
- LightningUsageByFlexiPageMetrics
Use the Event Monitoring Analytics App to monitor performance with event types
To measure EPT with the Event Monitoring Analytics App, use the prebuilt Lightning Performance dashboard. You can also use event types to monitor specific aspects of performance. Some useful event types include:
- Apex REST API
- Lightning Page View
- Lightning Error
- Lightning Interaction
- Lightning Performance
In addition to EPT, use browser developer tools to test network throttling, and use automation tools such as Selenium to test page flow performance. Write persona-based load generation scripts using tools such as LoadRunner or JMeter.
- In a single user performance test, you can look at a Lightning page with custom components. For that test, measure EPT, octane score, and network performance.
- In a large data volume test, you can look at a list view with many records and complex filters. For that test, focus on SOQL performance.
- When testing API performance, you can look at Account object updates using the SOAP API. For that test, measure request throughput and database time.
