It runs different on all machine...I mostly run amd's
it is an Improvement on the K6-2 machines that I use, but it mostly takes longer on my K6-3 machine...a real surprize...However with the right work unit my k6-3 will blow them by in about 11 hours, but usally 27 hours...but with version 2.04 my K6-3 is almost always 16 hours...
But it is almost about 3 to 4 hours faster on everything else....
Looks good on Intell p2/233 and p2/300....both with 64 meg of ram....
So try it on one of your machines and see....
