Thats a measure of the minimum extra overhead, in practice it will be a
lot higher as you will have to pull the data from the packet process it
wrapper it back up again and send it back.
Also remeber you have to reassemble the packets in the right order as the
ordering is not guaranteed.
I might try some benchmarks if anyone is interested. I'm guessing that you
really need gigabit though. IP over SCSI or 1395 might be an option, but
that's far more exotic.
