  Well, I've heard very bad things about that program.  Things like, HD crashes 
occuring much more frequently, and the reason you didn't see a lot of slow down
on an IBM 386/25 is that it IS a 32-bit processor, PLUS they are not mtasking,
meaning that the HD cruncher program can dedicated almost 100% of the CPU for
the crunching and loading.  ...
