Adam Slosarski has build a NUnit like application, to performance test parts of your application, just like NUnit does unit tests on part of your application. As you can see in the screenshot below, it has practically the same look and feel.
From what I can see at CodeProject, where the application is located, you can test what the performance is of your app as well as some other things, like how it performance with minimum CPU usage. Anyway, before I can say anything else, I want to test the application myself.
Meanwhile, you can [find it here](http://www.codeproject.com/dotnet/NTime.asp)…
