Have you disabled hyperthreading in the BIOS?
I did some disk I/O and CPU benchmarks, including bonnie++, hdparm, nbench, unixbench, dbench, tiotest. I haven't done any network/memory testing yet, the onboard Broadcom and Intel gigabit controllers both seem to work quite well. I have taken care to make sure that the 3ware card has its own PCI bus, in this case slot 5. I have not disabled hyperthreading but I am not sure why I would.
On that note, I have also done benchmarking with a Supermicro E7500 board (P4DPR, Intel Gigabit 82544GC onboard controller), the tests I ran included Netperf, Netperf3, NetPIPE (TCP), Tbench, nttcp, Aim9 and the ones I mentioned above. It seemed that if I had two identical machines hooked up directly (back to back with CAT5E crossover cable), the performance would be a lot better and is very consistent. I tried different combinations HT=on/off, CPU affinity, IRQ affinity, SMP/UP. Some results were:
Supermicro ========= Netperf Result (MB/s) - 112.21 Netperf3 Result (MB/s) - 112.22 Tbench Result (MB/s) - 114.48 Nttcp Result (Mb/s) - 946.55
However, if I hook it up to a different machine, problems started to occur. For example, with the Tyan S2720 Thunder i7500 board (E7500 chipset, Intel 82544EI onboard gigabit controller), I see good performance on the Tyan but not Supermicro.
Supermicro ========= Netperf Result (MB/s) - 29.23 Netperf3 Result (MB/s) - 78.19 Tbench Result (MB/s) - 117.32 Nttcp Result (Mb/s) - 646.77
Tyan ==== Netperf Result (MB/s) - 112.22 Netperf3 Result (MB/s) - 112.02 Tbench Result (MB/s) - can't find it Nttcp Result (Mb/s) - 945.9
