Marc (the QA lead) and myself (the Dev lead) of the VSTS profiler are sitting in front of Booth Dev-2 (Visual Studio Team System) in the Technical Learning Center.
The TLC should be opening up soon to customers, so I'd like to encourage you all to drop by. We'll be happy to help you profile your app or answer any questions you may have.
Also, mark your calendars as Marc and I will be delivering a Breakout Session entitled DEV313 - Improving Code Performance with Visual Studio Team System. We'll be covering a little bit of education about how to interpret the data coming out of the profiler and giving LOTS of demos of great new profiler scenarios in the next version including:
Web/Load Test integration
Comparing two performance reports
Line level sampling
and many more.
