Salesforce Performance Testing

Salesforce is a powerful CRM platform that offers great customization and integration capabilities and is adopted by more than 150,000 businesses around the globe. Though the platform itself is quite robust, the performance of a Salesforce application having custom code, configuration, integration, and data volume impacts user satisfaction and business success.

With its proactive approach to rigorous performance testing, the application detects API latency, data delays, and governor limit violations, resulting in outages being reduced by almost 80% , thus aligning with 99.99% uptime of Salesforce.

This guide explains in detail about Salesforce Performance Testing, strategies,, common limitations, and best practices.

What is SFDC or Salesforce Testing?

Testing in Salesforce (SFDC Testing) is validating whether a Salesforce implementation meets its functional and non-functional requirements for a project or system.

These consist of ensuring that configurations and customizations such as Apex code, Visualforce pages, Lightning components, integrations, and data flow function correctly and operate efficiently. Performance testing is considered one of the most critical types of non-functional testing for Salesforce applications.

Why conduct Performance Testing of a Salesforce application?

Performance testing is critical for Salesforce applications to ensure reliability, scalability, and user satisfaction, especially as businesses increasingly depend on customized and integrated Salesforce environments.

1. Prevent Revenue Loss and Downtime: Poor performance can directly impact revenue. Load and stress testing identify bottlenecks (e.g., API latency, inefficient code) that could cause outages during critical events like product launches or seasonal spikes .
2. Optimize Custom Code and Integrations: Over 60% of performance issues stem from custom code or third-party integrations. Rigorous testing validates these components under realistic workloads, ensuring they adhere to Salesforce’s governor limits (e.g., API call caps, CPU time) and avoid throttling.
3. Ensure Scalability and Resource Efficiency: Testing simulates growth scenarios (e.g., 10,000+ concurrent users) to verify the application scales without degrading performance. It also highlights inefficient queries or configurations that strain shared multi-tenant resources, which can degrade system-wide performance.
4. Enhance User Experience: Slow page loads or delayed transactions frustrate users, reducing productivity and adoption. Metrics like Experienced Page Time (EPT) measure usability, while endurance testing evaluates stability over extended periods.
5. Mitigate Business Risks: Proactive testing aligns with Salesforce’s 99.99% uptime SLA and prevents reputational damage from outages. For instance, stress testing uncovers integration failures or data retrieval delays before they disrupt operations.

Salesforce-Specific Performance Testing Considerations

Performance testing in Salesforce requires special attention due to its unique multi-tenant cloud architecture, extensive customizations, and integration complexities. Here are some of the Salesforce specific performance testing considerations:

1. Governor Limits: Salesforce imposes strict governor limits on resources like CPU time, SOQL queries, and DML operations per transaction. Performance tests must be designed to stay within these limits while still simulating realistic usage.
2. Multi-Tenant Architecture: Since Salesforce operates on a shared infrastructure, your org’s performance can vary depending on other tenants. It’s important to run tests at different times to capture variability and ensure stability.
3. Bulk Data Testing: Test how your Salesforce application behaves when handling large data volumes using tools like the Bulk API or Data Loader. This helps identify performance bottlenecks in data-heavy operations.
4. API Performance: Evaluate the response time and throughput of Salesforce REST and SOAP APIs under different load conditions. Be mindful of API usage limits and include composite and batch calls in your scenarios.
5. Lightning Component Performance: Test the loading and rendering speed of Lightning Web Components (LWC), especially for complex pages. Monitor Time to Interactive (TTI) and any JavaScript or re-rendering issues.
6. Custom Code & Triggers: Measure the execution time of Apex code, including triggers, classes, and workflows. Pay special attention to SOQL performance, recursion, and asynchronous operations like future methods or batch jobs.
7. Third-Party Integrations: Performance testing should cover external integrations, including latency, retries, and failure handling. This ensures that dependent services don’t become bottlenecks during peak usage.
8. User Load Simulation: Simulate concurrent users accessing the Salesforce application. Test scenarios should include login, navigation, data entry, and report generation under load.
9. Reporting & Dashboards: Complex reports and dashboards can impact performance, especially when filters and visualizations are used over large datasets. Include these in your test plan to assess their impact on response times.
10. Test in Appropriate Environments: Use a Full or Partial Copy Sandbox for realistic performance testing. Developer sandboxes are not suitable for load testing due to their limited resources.

How to do Salesforce Performance Testing?

Salesforce performance testing involves a structured approach that typically includes planning, scripting, execution, analysis, and reporting. It utilizes various types of testing to evaluate different aspects of the application’s performance:

1. Define Objectives and Scope

• Identify critical user workflows (e.g., lead conversion, report generation).
• Set measurable goals for response times, error rates, and throughput.

2. Configure a Production-Like Environment

• Replicate production settings, including data volumes, integrations, and third-party systems.
• Use sandbox environments for large data volume (LDV) testing.

3. Develop Test Scripts

• Use tools like JMeter to simulate user actions (e.g., API calls, UI interactions).
• Incorporate realistic test data mimicking real-world usage patterns.

4. Execute Tests

• Run load, stress, and spike tests while monitoring:
  • Application metrics: Response time, transaction success rate.
  • System resources: CPU/memory usage, database latency.
  • Integration performance: API response times and data consistency.

5. Analyze Results and Optimize

• Identify bottlenecks (e.g., inefficient Apex code, slow SOQL queries).
• Apply fixes like caching, database indexing, or code refactoring.
• Retest until benchmarks are met.

What are the Types of Salesforce Performance Testing?

Performance testing includes various methodologies designed to assess the functionality, reliability, and scalability of applications, particularly in the Salesforce environment. These testing types help identify potential bottlenecks and ensure that applications can handle user demands under different conditions.

• Load Testing: Under expected load conditions, this test will demonstrate how many users can access Salesforce at the same time. It shows how the application handles typical business operations traffic, thus helping with maximum capacity and the response times when for example hundreds of users generate reports at once.
• Endurance (Soak) Testing: Soak testing is run in extended periods with continuous steady load to uncover problems such as memory leaks or performance degradation. Thus it ensures that during extended use, Salesforce remains stable and responsive.
• Spike Testing: Evaluates how sudden, sharp increases in user load-that is, doubling user load in a very short period of time-affect Salesforce with instant traffic spikes. This helps define weaknesses where performance will be affected during promotions or peak seasons.
• Stress Testing: Pushes Salesforce beyond its normal operating limits to find the breaking point. This type of testing uncovers how the system behaves under extreme conditions and helps improve resilience against unexpected surges in usage.
• Scalability Testing: Assesses how Salesforce performs as user numbers, data volume, or transaction rates grow. This testing identifies architectural bottlenecks and ensures the system can scale to meet business growth without loss of performance.
• Capacity Testing: Tests to find the maximum number of users or transactions that Salesforce can handle without compromising performance, thus backing infrastructure and scaling decisions.
• Volume Testing: Checks how Salesforce behaves with huge data volume to ensure performance on bulk operations, like importing or exporting items in mass.
• Configuration Testing: Tests how the system performs on different configurations across various environments, such as different browsers, operating systems, or network conditions, to identify configuration-related issues that may negatively impact users.
