    Sounds like a duplex mis-match, which is especially
    common with unmanaged switches. The problem
    is that the computer and switch don't agree whether
    their link is full duplex or half duplex. The result is
    undetected collisions which must be retransmitted
    via TCP timeouts instead of being retransmitted right
    away by the NICs. I'd suggest setting the duplex on
    the switch ports if possible and devices to see if a
    combination works better, I'm not sure about the Mac
    but you can get a list of media options on FreeBSD
    using "ifconfig -m".

    Best wishes,
    anthony
