------------------------ Online Support ------------------------ To check for the latest news and updates regarding this tool you can go to the web site http://webtool.rte.microsoft.com. This web site contains a knowledge base that provides in-depth answers to performance testing questions and additional information on the most frequently asked questions.

------------------------ Known Issues ------------------------ Web Application Stress Tool only supports stress against one server or DNS name at a time. To use authentication, you must add users with valid user names and passwords. To record, you will need to modify your browser settings if using a browser other than, or prior to, IE 5.0. See online help for more information. Webtool respects the "user-agent: stress-agent" directive in the ROBOTS.TXT file on a web server and will not start a stress test against a server or domain that contains this file with this directive. This file should be located in the root directory of your web site

In general, you should NOT install the WebTool service on the web server you are testing since this may interfere with your results.

The Web Application Stress Tool object model can be used to start, stop, and configure a test run. However, this feature cannot be used to modify a running test in this version of the tool.

Web Application Stress Tool is year 2000 compliant.

IMPORTANT: Start your test with a small number of Concurrent Connections and then work your way up to the desired stress level slowly, watching the processor utilization on the clients and web server. If the processor utilization is consistently above 90% on one or more machines, the test is probably invalid. If this occurs, decrease the number of concurrent connections or add more client machines to handle the desired stress load.

On-line help contains a discussion of performance testing techniques.

Although there is no hard limit on the number of script items you can have in one script, the most practical limit is 3000 script items. Beyond that you will find that it takes an inordinately long time to start and stop tests.

Happy Testing, The Web Application Stress Tool Team
