Subject: Crafty is SLOW!!!

I have been comparing the top engines [on the same computer] by evaluating the
same position, sequentially, with each engine.  Many examples so far, but in
every case the time required to get to a given search depth is MUCH longer for
Crafty.  Why is that?  Also, does it matter in terms of playing strength?

Could it be that Crafty's findings at depth = 12 are just as good as Junior's
findings at depth = 16?

If Crafty could find a way to do just as much useful computation in half the
time [on the same computer], it would play better.  Right?  [Obviously.]

Maybe Crafty 19.03 is wasting too much time on non-essential
computations!!!!!!!!!!!!
