The tool lets you investigate the performance of the client side javascript! Ben and Emre explain how the profiling works, i.e. how they instrument the javascript on the fly, collect execution traces, and so forth. They also show a really cool demo of the tool where they turn on profiling for a couple web pages, then analyze the performance directly in Visual Studio.
