Finally got some numbers. The summary is it's in the noise, the average delta is +0.1s (total time is ~67s, so 0.17%) but the standard deviation is ~0.2s. So that's probably a real slow down, but it's very minor. I guess that's not surprising, given kernbench should be spending the bulk of its time in userspace. cheers
