This tutorial has introduced you to IBM Rational Performance Tester. In a very short time you were able to construct a test suite by recording a performance test for a Web application, customizing the test to randomize data upon playback, and using that test as part of a realistic performance test schedule. You executed that schedule on a small scale and used the near real-time reports to identify a slow page. Once you had identified the page, you gathered resource utilization data and response-time breakdown statistics, which you then used to investigate possible hardware and software causes. You then drilled down to the specific source code method causing the problem.
While you may have learned a lot in this tutorial, you have only scratched the surface of what Performance Tester can do. As you continue to explore Performance Tester you will discover many more features to assist you in testing the performance of your applications and releasing them with confidence.
