Go up one level in this thread


Unfortunately I don't have dual P4/2.8, but here are some numbers:

Single P4/2GHz:     806k nps
Single P4/2.53MHz: 1.07k nps
Dual P4/2GHz:      1.48M nps.

As you see, P4 scaled better than linearly from 2GHz to 2.53GHz (1.33x when CPU
speed up by 1.265x); probably faster memory helped. I estimate that dual
P4/2.53GHz will be in the range 1.8-1.9M nps.

And dual P4/2.8GHz would be even faster.

Thanks,
Eugene
