I'm looking for an open source C# ASP.NET Web App that can be loaded onto 2 or more dedicated servers and provide me with metrics on how that server is performing. E.g. Click on a page and the app does a number of in-memory iterations and/or calculations to test processor throughput. Another page would do a bunch of disk access and report on that.

I could put one together myself but there might already be something out there with a whole ton of tools in it to do this. I would imagine that I'm not the first one that would want to compare two machines for use as a web server.
