Copies to: [EMAIL PROTECTED
For some reason, I am at a loss to explain, a v21 P4 1.4 GHz factors
significantely slower that a P3 v20 700MHz. Is there a reason, and solution,
for this?

Good question.
AFAIK George has done nothing to the factoring code. You will see a
BTW there was an unreasonable acceleration of trial factoring
between the P5 architecture (Pentium Classic/MMX) and the P6
architecture (Pentium Pro / PII / PIII / Celeron / Xeon), so you
can't simply assume that Intel doesn't care about integer
performance!
But they clearly don't care

Hmmm... Good question...
AFAIK, the only change George has or is going to make in the
factoring code since
