Running deep rybka 4.1 32bit:  On my old P4(hyper thread turned off) @ 2.8GHz, I get 30kN/s

Running deep rybka 4.1 32bit:  On a dual processor xeon server @ 3.8GHz I get the exact same speed 30kN/s

I've used a few different GUIs (arena, COW), same results, I see two processes of deep rybka running on the multiproc machine, but do not understand why the search speed ends up the same.

Am I doing anything wrong?

Reading some of the Node rates you guys post makes me embarrassed of my hardware.

PS. Is there anything beyond rebooting that I can do to avoid 1450 error on large tables?  I get it even after a reboot on a machine with 2GB of ram.  Does running in safe mode help?
