I want to load test an ASP.NET web service. I have Visual Studio 2008 Professional Edition and Visual Studio 2010.

Can either one of these products facilitate load testing? I can't seem to find anything and all Google returns is higher end editions of Visual Studio.

If not, what are some of the alternatives.

Or better yet, is there a product where I can feed it an IIS log and it will essentially replay it?

Is there a cheaper way to do load testing than upgrading to Visual Studio 2010 Ultimate
and also there was a tool called "MICROSOFT WEB APPLICATION STRESS TOOL" but i couldnt find its download apperantely MS removed it from its official page. check this forum for download link http://forums.iis.net/t/1161284.aspx for usage http://www.west-wind.com/presentations/webstress/webstress.htm
