The question I have not seen the answer yet to is “why?”
Is this really because of the network, e.g., separate pipes in some places still, with forwarding devices handling a lot less pps?
Is it because of people having done a newer cleaner-cut network stack implementation and lately cared about its performance?
Is it about middle nodes?
Has anyone done the research on this?.
The life of an IPv4 packet on the Internet is very likely to undergo some NAT at some point in its travels. I haven't yet heard of many doing NAT66, hence IPv6 not undergoing NAT means any slow-downs caused by NAT44 are missed (gladly) on IPv6. This might not necessarily be immediately visible on regular networks, but the large content players could count this quite easily due to the significant volumes of traffic their networks are having to aggregate and process.
