Interesting. I always imagined that iSCSI was going to be the clear
winner in the case of one NIC as the hardware offloading should more
than compensate for the overhead of TCP, but I guess you lose all of
that when you start bonding links together, especially on the receive
side of things.

Some adapters have iSCSI specific acceleration, but I don't know if that
works with bonding at any level.
