are you talking about JUMBO frames? or am I missing something.
Increasing the size of the MTU in a gigabit network, you might be
suprised with the results. Also, not all cards are created equal,
look for ones with tcp/ip checksum offloading n stuff. The less
interupts the better, as it takes so so so long for the processer to
handle the request, it's a shame you can't get networks cards with
direct dma transfers...,like scsi.... ;-).

Laters,
