Willy is talking about a 'feature' called tcp-stack offloading. It's a
pile of crap, a generally rotten idea. There are some things that you
can offload to the NIC nicely [checksumming, etc] but a whole tcp
stack? Pure evil. Avoid.

As to the original question - David, have you been keeping metrics on
latency and throughput? You really need to analyse this a bit more
thouroughly.
