For what it's worth, I tried running the test on a dual processor Xeon, 
a dual core Athlon 64, and a single core Celeron D. In all cases was 
QueryPerformanceCounter the slowest by at least a factor 5 to the 
closest. GetTickCount was the fastest, and timeGetTime and the Pentium 
counter traded places in the middle depending on computer.
