F11-302: Interpreting Performance Testing Results

Track: Performance Testing

You’ve worked hard to define, develop and execute a performance test on a new application to determine its behavior under load. Your initial test results have filled a couple of 52 gallon drums with numbers. Now what? Crank out a bunch of graphs, send them out, and call yourself done?


In this session we’ll look at my CAVIAR process for evaluating test results:

  • Collecting
  • Aggregating
  • Visualizing
  • Interpreting
  • Analyzing
  • Reporting

Then together we’ll look at example graphs taken from actual projects and interpret them to see what hypotheses we can glean.

Finally, I’ll share with you my approach to reporting results in a clear and compelling manner, with data-supported observations, conclusions drawn from these observations, and actionable recommendations.

I guarantee that you will take home at least one new idea that will make you a more effective performance tester.
