uh, "slightly better" at doing what? For pure networking, for example, a single 3.2 Xeon will outperform a dual opteron in most cases, but perhaps not at tasks that are well suited for multiprocessing. Factors like whether your NICs are on separate (tunneled) busses, whether you're using pci-express, etc will have a rather large impact on results. Its not just an "is A better than B" issue. And results will vary from MB to MB. "Most" opteron motherboards are not optimized to use the processor to its full advantages. Two different motherboards using exactly the SAME processor will have possibly substantial performance differences, so its rather difficult to compare different make processors that don't run on the same MB without qualifying the results. All you can really say is that Processor A on THIS motherboard performs better than Processor B on THAT motherboard when doing THIS particular task. _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
