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. ] -- Darryl Okahata darrylo@sr.hp.com DISCLAIMER: this message is the author's personal opinion and does not constitute the support, opinion, or policy of Hewlett-Packard, or of the little green men that have been following him all day.
