That would be good for a 64 CPU machine of course, max=6400% there. >But on an 8-way box I assume something in the CPU time is wrong. In fact, I >seem to remember that Sun did something odd.

That would make the above >numbers make sense. Divide by 8 since the CPU time is off by a factor of 8, and >the numbers look like 593%, 604%, 637% and so forth... This is true for Mac OS X also (maybe for any BSD-derived Unix ?) -- crafty reports 396% for my dual. Frank
