For what it's worth, I have been able to send and receive 400+ Mbps
of traffic, by directional, on the same machine (ie, about 1600 Mbps
of payload across the PCI bus)

So, it's probably not the e1000 or networking code that is slowing you down.
(This was on a 64/66 PCI, Dual-AMD 2Ghz machine though,
are you running only 32/33 PCI?  If not, where did you find this motherboard!)

Have you tried just reading the information from disk and doing everying except
the final 'send/write/sendto' ?  That would help determine if it is your
file reads that are killing you.
