I wasn't going to answer, because I don't know how much I *don't* know about his, but seeing as no one has I'll give it a shot. Intel's implementation of dual core (at least on Pentium 4 and Xeon) is pretty much two CPUs in one package. They still connect to the northbridge individually, i.e. they still share the bandwidth of the FSB. Thus I don't think there should be any difference between the performance of a dual Xeon setup and a single dual core Xeon. If you were talking Opteron, a dual CPU might outperform a dual core slightly, simply because the Opterons CPUs each have it's own memory bank to itself, so a dual core is sharing one memory interface between cores (where Xeons share it either ways so there's no gain). I don't know what sort of gain we're talking about tho - depends on how memory intensive amavisd-new is. But if you're running a RAM disk, it might just be substantial > Any throughput differences in message processing? Especially with a full > rule set (including SARE's rules)? I would imagine just make sure you have enough memory. Hans ------------------------------------------------------- Using Tomcat but need to do more? Need to support web services, security?
