You can achieve about ~20 us messaging latency for small messages
if you use M-VIA on (DEC Tulip) FastEthernet. Vanilla Linux TCP/IP gives
you ~60 us. A cut-through switch introduces a few us overhead. With
the channel bonding kernel patch one can coalesce up to 4 NICs into
one channel, all of them running full-duplex.

Myrinet, mostly.
