Was just trying to get more info from large networks about whether how some of the things that make theoretical logical sense actually work out in practice that way e.g. whether fixed header size and the fewer headers required to decode to read an IPv6 packet (with respect to IPv4) really may provide some signifiant performance advantages.
So far, all indications are that the fixed header size means nothing, in terms of speed, but the *extension* headers are a significant complication and source of problems. Some of the other claims (e.g. more secure because IPsec is always available) are simply wrong - there is plenty of IPv6 equipment that doesn't offer IPsec.
