There is a huge amount of information available on the how's and why's of performance testing .NET applications, but it is often fairly subjective, narrow in scope, or doesn't quite cover everything you were hoping to learn. The Complete Guide to Performance Testing and Optimizing .NET Applications (by Paul Glavich and Chris Farrell) covers everything from why you should test, through the steps of setting up your test environment, all the way to how to actually run and record tests, and what you should be looking for. Once you're up and running, Paul and Chris cover the fine details of tips and techniques to make the most of your performance testing, and some good ways to get fast results. With all this detail, you will have everything you need to make the most of your .NET code.
