    from my multiple 64/66 PCI bus + multiple 2gbit/s FC HBA tests, yes,
    they're around the same.
    (now up to 390mbyte/sec throughput on latest & greatest x86 hardware i
    have; front-side-bus no longer the limiting factor, but dual 64/66 PCI).

    of course, purely synthetic tests designed to stress Fibre Channel
    switching infrastructure, not real-world disk i/o..
