Closed Captioning text:This tour is a quick overview of what you can do with Rational Performance Tester.

Page text:Welcome to the IBM Rational Performance Tester tour.


Page title:Performance testing

Closed Captioning text:Rational Performance Tester guides you through the easy creation and modification of performance tests against Web applications.

Page text:With Rational Performance Tester you can perform the following tasks:Create tests by recording typical user actionsEdit tests to include variable dataEmulate multi-user workloads with schedulesEvaluate results during and after a run


Page title:Creating a recording

Closed Captioning text:You work on performance tests within the Test perspective of the IBM Rational Software Developer platform. To create a recording, start the recorder, provide a name for the test, and then navigate through your Web application as a typical user does. Closing the browser displays the results.

Page title:Editing a performance test

Closed Captioning text:In the test editor, you can customize any performance test. You can add comments, loops, conditions, and transactions to your performance test.

Page title:Using datapools

Closed Captioning text:You can use Rational Performance Tester to create datapools, or you can import comma delimited files that already contain the variable data.

Page text:Enhance your recordings by using datapools:Supply data values that vary from the recorded valuesProvide more realistic results


Page title:Setting a schedule

Closed Captioning text:You run a performance test by setting up a schedule of user interactions. A schedule is a controlled, flexible way to create the test scenarios to be done by virtual users.

Page text:You can specify the overall performance test characteristics:Add user groups and testsSet loops, delays, and think timeRun from remote locations


Page title:Emulating a single user

Closed Captioning text:You can run a single-user test for debugging and getting datapool values and correlations to work properly.

Page text:A schedule can be as simple as having one virtual user running one performance test...


Page title:Emulating multiple users

Closed Captioning text:You can run a multi-user test for tuning services and measuring overall system performance.

Page text:...or as complex as hundreds of virtual users running multiple performance tests concurrently or at different times.


Page title:Analyzing test data

Closed Captioning text:Rational Performance Tester provides a performance report for analyzing your test data. This report is updated during a run and is available after a test run.

Page text:The Overall tab displays dynamically the state of the test execution.


Page title:Summary

Closed Captioning text:The Summary tab outlines the most important data about the test run, so that you can analyze the final or intermediate results of a test at a glance. It includes detailed counts of all activities, their timings, and results of verification points in the test execution.

Page text:The summary shows the final results at a glance.


Page title:Page Performance

Closed Captioning text:The Page Performance tab provides the average load time of all pages accessed during a test run. With this information, you can evaluate system response during and after the test.

Page text:The response trend of the 10 slowest pages is displayed in the Page Performance tab.


Page title:Response vs. Time Summary

Closed Captioning text:You can see how your application performs over time in the Response vs. Time Summary tab. Each point on the graph is an average of what occurred during that indicated interval.

Page text:Average response times are graphed for all pages (Page Response vs. Time graph) and all page elements (Page Element Response vs. Time graph).


Page title:Page Throughput

Closed Captioning text:The Page Throughput tab enables you to monitor the ability of your server network to keep up with the workload. The page hit rate gives an overall indication of how many requests are being made to the server during every sampled time interval for the duration of the test.

Page text:Page Throughput provides an overview of the frequency of requests being transferred per interval.


Page title:Resource monitoring

Closed Captioning text:Resource monitoring data can provide a more extensive view of a client computer using the application to aid in problem determination. The Resources tab shows all resource counters monitored during the schedule run.

Page text:Resource monitoring enables you to collect system resource data, such as CPU or memory usage.


Page title:Conclusion

Closed Captioning text:Your next step is to explore the tutorials and other learning aids found in the Welcome page. We hope you find them useful and informative.
