I\'ve noticed since installing Visual Studio 2010 SP1 that I\'m having huge performance issues. It will randomly freeze up on me quite a bit.
I had no performance issues
I emailed ReSharper support and they were helpful enough to point out that there is a known issue with the Productivity Power tools add-on not playing nice with ReSharper. They asked me to disable the Productivity Power Tools and see if performance returned to normal.
I disabled the Productivity Power Tools and my Visual Studio with SP1 seems to behave normally again. This is an acceptable solution for me since the only part of the tools I used was the Document Tab Well, the rest seem pretty worthless to me. JetBrains is a really good company so I'm sure they will work on resolving the issue, or at least work with MS to determine which the problem is caused by.
Though my own hunch has me thinking the Productivity Power Tools are the culprit and not ReSharper.
Kind of ironic that the "Productivity" Power Tools were making me much less productive.
