You're saying that people should just go and use jumbo frames? Isn't
that a problem for mixed 10/100/1000 LANs?
No, I'm saying that the current situation is fine with most cards
and most uses.
Ben pointed out that interrupt-mitigation challenged cards like the
NatSemi do gain, but that is the only case I can imagine at this
time.
Unless you have a card like the NatSemi (no interrupt mitigation) or
your interfaces are being hit with 120,000 packets per second EACH,
then NAPI is not going to be an explosive gain for you.
Look, we were able to get world records in web serving without NAPI,
right? :-)
