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.
