WCAT Fiddler Extension for Web Server Performance Tests
For web server performance testing the Microsoft Web Capacity Analysis Tool (WCAT) is the tool of choice of the IIS team as well as the Windows Performance Team. Simple tests that hammer IIS with thousands of requests to the same HTTP page to very sophisticated web hosting and benchmark scenarios - there is nothing that WCAT can't do. Even on ApacheCon I heard some hard-core Apache guys talking about using WCAT for their performance tests.

Careful when using the Cache-Control Header UI in IIS 7.x!
I was just reading Eric Lawrence's blog on Cache headers. In it Eric describes that it's necessary to use sensible values for the Max-Age headers because IE and several browsers don't like values greater than the size of a signed 32-Bit Integer, i.e. 2,147,483,647. Bigger values result in the content not being cached at all. Using the max 32-Bit integer value (2,147,483,647) is more than enough though. It caches the content for more than 68 years (max-age is using seconds so you divide 2,147,483,647 by 60 seconds by 60 minutes by 24 hours by 365 days which gets us to 68 years).
