Code compiles faster on x64
At Microsoft, I’m told that we’ve switched to using x64 machines to compile our Windows operating systems, and the effects have been stunning. Windows Server 2003 Service Pack 1 took 9 hours to compile on x86 machines, but just 3 hours on x64s. Longhorn took 18 hours to build on x86 machines, but just 6 hours on x64s!
So code will compile in about 1/3 the time on an x64 processor. I really wish Dell would start selling AMD stuff, those lousy luddites.
