Question: 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 with Visual Studio 2010 before the upgrade. The only add-on I have running is ReSharper.

I'm wondering if anyone else is experiencing performance issues? If so have you found a way to fix them?

Answer: 
Just a small heads up about SP1: 

* If you have SQL Server Management Studio installed on the same machine, **don't** install SP1 just yet. You will lose all intellisense functionality. This is a major bug that must of slipped through.

In terms of performance, I haven't really noticed much of a difference.
I have tried to use VS 2010 only once, and I am glad we are not upgrading to it for my project. We have to shut down all other applications before we start it. Even then it can take a good 10 minutes to load. We will need the latest PC config with lots of RAM and the latest OS to get it any faster than that.
