In that case, no reason for it.  I just ran on my wife's pentium pro 200, using
win95, winboard and crafty 15.18 (as released).  The NPS didn't change whether
I ran crafty in a dos window or under a stock winboard 4.0 that I downloaded to
test that machine.

So no idea why you see it slow down by 1/3...

I know of many using winboard to play (running crafty) on ICC... we don't see
this at all..
