My situation
In the C# project I am now working on we have a fairly big solution (80+ projects). Now rebuild times of 5 minutes+ are really becoming qui
If you got enough RAM and are using Visual C++ (not sure about C#), you could accelerate things by copying the whole include and lib directory to a RAM drive.
You can also place the temporary build items to be on the RAM drive. Of course you need a massive amount of RAM. A 2 GB RAM drive would be enough for the includes and libraries. But for the temporary files (*.obj, etc.) it would depend on the project. So it might be between 1 and 4 GB extra or more.
