I guess the fairly spectacular differences (in the P-III results) are
mainly due to compiler differences? Could all three of you guys confirm
the details of your systems (RAM, mobo, compilers+flags, (OS!) etc)?
I'm surprised that the differences are quite as big as they are between
the two P-III machines.
