The baseline metrics, including the test configuration, environment, and other relevant details, are then documented. This documentation serves as a reference for future tests and enables accurate comparisons.

Step 5: Future Test Comparisons

Once the baseline is established, future tests are conducted using the same or similar test scenarios to evaluate the system’s performance under different conditions or after modifications. The performance metrics from these subsequent tests are compared against the baseline metrics to identify any deviations or improvements. This comparison helps detect performance regressions, bottlenecks, or unexpected changes in behavior.

Step 6: Troubleshooting and Optimization

Further investigation and troubleshooting can be initiated if any discrepancies or performance issues are identified during the comparison. The baseline metrics act as a valuable point of reference for understanding the expected performance and diagnosing the root causes of any observed deviations. This allows organizations to optimize the system or application to improve performance and ensure it meets the desired standards.

Following these steps, baseline testing enables organizations to establish a performance benchmark, track performance changes over time and proactively address performance-related concerns. It provides a solid foundation for performance testing and optimization, ensuring that systems and software applications deliver the desired performance and user experience.
