You are not alone... That one just started on this machine... 148 minutes per frame??? That can't be right, can it?
Nope. It'll take a while to sort itself out, I think. Mine is 20 seconds per frame on a 3gig pentium.
I don't think frames are always the same size. I had a 10,000 frame protein that was folding at 1 frame/22 s. Then I've had 500 frame proteins folding at 1 frame/3.5 min. Once it benchmarks properly it should settle down at a more reasonable value of probably 3-7 minutes.
