    I will be putting together a dual Opteron this weekend with the hope
    of testing network throughput.
    Spec will be:
    Dual 244, 2Gb RAM, 5x400Gb SATA RAID 5 on a Highpoint 1820a
    Broadcom 5705, Intel gE and a Intel dual port ( PCI 32 ) for comparison.

    Will let you know the results.

        Steve

    Yes. The 3ware card and the Dual Port em are both in the PCI-X 100
    slots (the first two).
    There are no 32bit cards in the machine.

    Is there some method I can use to determine if the PCI bus is the
    bottleneck or even to determine the level of contention on the bus?

    I've been looking at the newer Opteron boards with multiple PCI buses
    but that's a lot of money to spend on my hunch.
