I think that the Load Testing capabilities within Team System Test Edition and the Load Test Agent are really still just waiting to be discovered by the majority of our users. When they do, they're in for a very big surprise. As an example of what these tools can do for an organization, Ed Glas recently posted details about the experience of the adCenter Display Ads Platform team and their use of Team System. Pretty impressive results including running 42 agents generating 3,639,518,000 requests. Check out the details here: http://blogs.msdn.com/edglas/archive/2008/03/17/84-248-ads-per-second.aspx.
