Is ReSharper 5.1 slowing down Visual Studio?

I recently had some slowdowns that I attributed to ReSharper.  On every file save, the machine would freeze for a good 1-2 seconds.  That gets old really quickly.  Disabling ReSharper fixes the issue, but a fellow developer had no issues with speed with all the same settings.  After fighting with it for a couple days I finally remember to try and turn off VisualHG, my source control plugin.  After turning it off, the problem is gone and I can re-enable ReSharper.  I would much rather have ReSharper than VisualHG.  I typically never use VisualHG, it’s just never been a problem before so I left it on.  I’m not sure which team is responsible (if any) for the conflict, but I hope this post helps someone out.

If you use Visual Studio 2010 and have random slowdowns or aren’t impressed with the speed in general, you should be running Visual Studio PerfWatson.  Read more here. Developers owe it to themselves to run this plugin and report anything.  I’m hoping the IE9 feature that tells you which plugins are resulting in a slow startup time makes its way to Visual Studio as well.  That way the pressure for the best feature of any software, speed, is placed squarely on the developers of the plugins.
