You don't understand, the person who mangles the packet must make the copy, not the person not doing the packet modifications. for a "high performance app" requiring gigabit-type speeds, ...we probably won't be using ppc64 and e1000 cards, yes, I agree :-) Anton, go to the local computer store and pick up some tg3 cards or a bunch of Taiwan specials :-)
