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 haven't noticed this problem, but Scott Guthrie's blog entry on SP1 indicated near the end that VS SP1 now uses software rendering rather than hardware rendering. This can cause perf issues for some. You may want to check this out. You can access the setting in Tools | Options on the Environment/General dialog.
Installing sp1 has definitely made visual studio 2010 slower. Finding VS 2010 a bit dissapointing. Having said that, sp1 by default turns off hardware graphics acceleration in the tools options dialog. If you turn that back on and turn off rich client visual experience then things get a bit faster (I think).
