Possibly, yes. > I notice that the timing numbers on the hurd are usually round > numbers, so could there be problems with the timers? It's simply that for more precise timing you need to use the HPET driver, which is available only with an acpi-enabled kernel. I wouldn't bother, though, the measurement is still representative, if not very precise. > I would think that on this CPU the lack of SMP on gnumach would not > explain such difference. These look like single-threaded tests indeed. Most tests are fine, the only ones that I see odd are 1: BM_ManualTiming/1/real_time 19999981 ns It's probably simply waiting for a whole clock tick (10ms) for some reason. Probably worth having some look at what it actually does, precisely. Samuel
