Web Performance Trainer 2.6
This is Web-load testing and Web-stress testing software and tools targeted at Web sites that use standard technologies such as Web forms, J2EE, ASP, .NET, PHP, ColdFusion and Java.
Its automatic analysis can tell you how many users your Web site is capable of handling at one time using your own unique performance criteria. Because data is collected at the URL level, it not only identifies slow Web pages, but also identifies the particular part of the Web page that caused the problem. Simulate up to 500 users from a single test computer, or install load generating "engines" on multiple computers. The program has features such as IP spoofing, client certificates, multiple simultaneous test cases, authentication (usernames/passwords), SSL recording and playback, and automated analysis.
