I believe that using wall-clock timers for benchmarking is not a good approach due to the high noise level. Process time timers typically have a lower resolution, but give a better picture of the actual run-time of your code and also don't exhibit as much noise as the wall-clock timer approach.

please stop repeating this nonsense. there are no "process time timers" in con- temporary operating systems; only tick counters.

there are patches for linux and commercial add-ons to most platforms that lets you use hardware performance counters for process stuff, but there's no way to emulate that by playing with different existing Unix or Win32 API:s; the thing you think you're using simply isn't there.
