Yes a very big difference.  My time control was 20 moves in 60 minutes
(3min/move).  Do you see the difference now?

No.  I meant to say 2-3M nps and that's because Bob seems to get that from his
machine.  Also it was followed by a smiley face to indicate I was jokeing with
Jorge's remark about Shredder being tuned for 1200 Mhz.
