Also note that, with SMP and Celerons, the 66MHz FSB may be an
issue. If Amancio is right, and buildworld is memory bound, then a
100MHz FSB may give a noticeable improvement.
[ I should try to write a benchmark that tests memory contention and
SMP. I've got a similar system to yours, except that I've got striped
SCSI disks. I've never done a buildworld; perhaps it's time I did. ]
