Why is Visual Studio 2010 reading project files continously?

I turned process monitoring on and I noticed that vs 2010 doesn't stand still, it continuously reads the project files in the solution. Wtf?

I have this solution that progressively becomes slower and slower to the point where when I type in the C# editor the letters appear a few seconds later.

Below there is some info about the environment:

Is there anything I can do? And I am using TFS.

After more usage, I noticed that it has to do with Resharper and running multiple instances of Visual Studio. As soon as I start having 3 or more instances vs2010 slows down. I also reported this issue to the Resharper folks.

Without resharper the ide was fast - I haven't tried though running multiple instances without resharper.

Since I love resharper I now use only one instance of vs 2010 and open others only when I need them and close them as soon as I don't need them.
