No HT enabled CPU will be the same as 2 physical processors. HT is just a second set of processing gates on the CPU. The cache and other items are shared between the 2 sets of processing gates, so it's quite less of an enhancement than a second physical CPU. That said, it is more (some times quite a bit) power than a single CPU w/out HT. -- Jesse Keating RHCE MCSE http://geek.j2solutions.net Mondo DevTeam (www.mondorescue.org) Was I helpful?
