Comparing performance results

You can analyze multiple load groups side by side, to understand how different workloads affect the system under test.

1. Toggle on the Compare option.
2. Select which load groups to include in the comparison.
   Note: In the current version, comparison is only available within the same scenario run. Historical runs cannot be compared, but this capability will be introduced in a future release.
3. Interpret the results.
   • Color coding: Each selected load group is highlighted with its own color. These colors are applied consistently across all charts, making it easy to distinguish results.
   • Overlayed charts: Metrics such as HTTP response time, error rates, automation step duration, CPU, and memory usage are displayed in overlayed graphs, so you can directly see how one group’s behavior correlates with another.
   • Use cases: This feature helps identify interaction effects—such as whether an API load spike slows down a web transaction flow or if concurrent processes compete for the same resources.
