1. I was using ReSharper with some code with 3000 - 4000 lines of code in one page. If I modify anything, it will cause 100% CPU for good 3-4 seconds and slow down UI somewhat.
2. On the other project, I also experienced the hanging problem where VS.NET stopped respond for about 30 seconds with no CPU load.
3. On another project which is very big (5000-6000 files in a web project), it takes about 5 minutes to open up the solution.
Don't need to fix it now :P Just remind you guys
