I have only tested the compiler speed on a single project. It was a rather large one, just about 200.000 lines. It was an typical MFC application. VC7 was actually about 20 - 25% faster than VC6 for a rebuild... J Cardinal wrote: Is there any advantage that VS.NET can utilize if I were to go with more than one CPU? Nope, I have a dual processor workstation, and VS.NET only use 1 cpu for compiling. (but your computer is fast if you wanna do something else while compiling ;) ) - Anders Money talks, but all mine ever says is "Goodbye!"
