1. What is the hardware configuration of the PC with ReSharper? What
Windows version are you using?
Operating System: Windows 7 Enterprise 64-bit (6.1, Build 7601) Service
Pack 1
Processor: Intel(R) Core(TM)2 Duo CPU E6750 @ 2.66GHz (2 CPUs),
~2.7GHz
Memory: 8192MB RAM
Page File: 5959MB used, 10290MB available
Video Card: NVIDIA GeForce 8800 GS
Monitors: 2 at 1680 x 1050
Harddrive:
o 240gb (130gb primary partition for OS and apps, remainder for file store)
o write speed of 96.5 MB/s and read of 86.0 MB/s (using aja system test)
Visual Studio 2010 Ultimate
2. Could you describe your solution structure: how many projects and files
are there, what type of files do you use, etc.?

We have a ridiculous number of solutions, but here's the specifics on the
one that I spend the most time in is a VB.Net based web app. The solution
looks like this:
Primary project ASP Web App (VB.Net)
o 1870+ total "include=" items in the .vbproj file.
o 28 of them are ferences
o 10 are imports
o 454 are compile includes
o 1248 content inculdes
o Rest are a mix of resources, references, non includes, folders, etc.
One C# library project with 32 include= items.
One C# test project with 116 include= items.
One website project (no compiling, just there for shared resources, like
JS, css, etc).
3. Have you noticed any features/scenarios that are making Visual Studio to
slow down?

Just about everything is slow, I suspect it has alot to do with the project
size. disabling solution wide analysis doesn't seem to make a difference.
I've noticed extreme slowness in larger files, especially large files that
reference other large files (such as a large db class that inherit from
another large db class). Classes that have alot of lines (some of them
1000+, got to love legacy code) are particularly heinous.

4. Are there any other 3rd-party Visual Studio extensions installed?

Yes, but even with them disabled, I noticed huge performance problems. In
the original benchmarking, I had disabled everything except for ReSharper.

5. Also, does Visual Studio operate much faster without ReSharper?

Yes.
