However, PIII processors will only do 2 way processing. Meaning, you can only use 2. To get 4 way on x86, you must use Xeon. I also know that FreeBSD does not do SMP very well as opposed to it's counterparts. We use FreeBSD for our webservers and openbsd for our firewalls and unfortuneatly Suns for our databases because of their support for Oracle as well as the ability to have 8+ processors. Like I said before, would this money not be better spent on ram and raid? =) -Chris Phillips On Thu, 11 May 2000, Mitch Vincent wrote: > Oh, one more thing.. > > Why would I need XEON processors?
