Today I installed the Visual Studio PerfWatson extension. Briefly, it automatically reports when Visual Studio hangs (for > 2 seconds) to Microsoft so that they can one day fix it.
But a nicety is the PerfWatson Monitor extension, which adds a cool little graphic it adds to the bottom of Visual Studio:
Since I’m running Visual Studio on my lowely netbook which constantly hangs (i.e. doesn’t respond for a few seconds), Microsoft will be getting plenty of data from me!
The Perf Watson blog is here but if you want to install it just go to Tools -> Extension Manager (in VS) and search for Watson in the Online Gallery. Install Visual Studio PerfWatson and PerfWatson Monitor.
