the standard deviation in the values; I don't have another 8-way by hand, but a 4-way 6-STABLE gives : cpu0: timer 3299774936 2000 cpu2: timer 3299757640 2000 cpu3: timer 3299757640 2000 cpu1: timer 3299757640 2000 and my 8-STABLE notebook (with kern.hz=100) : cpu0: timer 323161363 400 cpu1: timer 323161114 400 A range from 9 to 199 is 'funny', maybe I choose the wrong word, but I didn't see such discrepancies before.
