Compare Performance Reports

The Compare Performance report compares response times measured by
Performance reports. After you have generated several Performance reports, you can
use a Compare Performance report to compare the values of a specific field in each of
those reports. You also can compare reports that show different numbers of virtual
testers or compare reports from runs on different system configurations.

Compare Performance reports allow you to see how benchmark information differs
for various workloads. For example, you can run the same test with increasing
workloads, and then compare the Performance reports of the test runs to see how
performance changes under an ever increasing workload.

When you run a Compare Performance report, you specify the base Performance
report and up to six other Performance reports.
