Suggested Web Stress Test Scenarios

does anyone know of any web application stress testing "best practice" documents? I'm about to load test a .NET 4 site using VS2010's tester and would like to have an outline to work from to ensure i'm covering all my bases (or as many as possible).

So for instance,开发者_StackOverflow id hope that the document would be the type that says, "try pushing x users over y time" and "x concurrent users over y time." But then again i have no idea. Thats why i need your help.

Thanks all, very appreciated.

have you seen the article on .NET application performance testing from MSDN? http://msdn.microsoft.com/en-us/library/ff647788.aspx
