> How exactly is ipv6 more performing? It even has bigger headers. This is something I don't really see anybody mention, but IPv6 doesn't allow packet fragmentation as far as I know -- which means you don't get the sudden performance degredation (and extra data loss probability, etc.) that comes with using the wrong packet size. I expect that boosts performance but I haven't had a chance to measure.
