You misunderstood the process, you need reference conditions to measure something, I just set it to 1GHz P3. With a load of 2 without swapping, that reference just would have been a 500MHz P3, but that's still an arbirary choice :). When swapping or heavy I/O all bets are off anyway (with 2.4 kernels at least). Laurent
