On Windows, we use QueryPerformanceCounter and QueryPerformanceFrequency to calculate elapsed time in the main server loop. There is also some startup code which measures CPU clock speed by calling QPC in a loop until 1/32 of a second has elapsed, but we only use this to estimate CPU speed for crash reports.
