VS 2010: What is the ++ file symbol on the status bar?

Every time I open Tortoise SVN project (lots of code) in Visual Studio 2010 it will suddenly start doing something that leads to my HDD actively working and this leads to my computer (and VS as well) getting super luggish. I noticed there's a "++" icon near main windows bottom right next to line number and column number:

that is almost always animated at the times I see the slowdown.

What's that icon for? How can I disable or make more friendly开发者_开发知识库 the activity that slows my computer down?

1. Open up Task Manager (or better yet Process Explorer).

2. Under the View menu add columns for I/O Reads

3. Sort by that column

4. Open your Tortoise SVN project

5. Watch what process is changing the most

I've seen both Intellisense and Tortoise SVN both slow things down a bunch as the commenters above have suggested.
