By simulating load for your application, you can test concurrency issues as well as better understand how your application behaves under stress. Testing load and concurrency by refreshing a browser is not considered a valid test. MORE INFORMATION ================ Following is a list of Web stress tools available from Microsoft. The following files are available for download from the Microsoft Download Center: - Web Application Stress Tool (http://webtool.rte.microsoft.com) - (Web Capacity Analysis Tool) Download Wcat.exe now - Download InetMonitor now (http://www.microsoft.com/siteserver/site/DeployAdmin/InetMonitor.htm) For additional information about how to download Microsoft Support files, click the article number below to view the article in the Microsoft Knowledge Base: Q119591 How to Obtain Microsoft Support Files from Online Services Microsoft used the most current virus detection software available on the date of posting to scan this file for viruses.

With these tools you can stress test your Web server to see how it reacts when several hundred users access your application at peak times. These tools can also be used to test the server-side components for performance, locks, and other scalability issues. A Web application that relies on databases can also be tested on parameters such as concurrency, transactions, number of users, locks, pooling, and so forth.
