I doubt that CGNAT will make a measurable speed difference for
99.99% of applications. Some will have to do additional negotiations
to open up port and as the CGNAT is at the other end of the pipe
that will take a little longer but not noticably.
That's one of the reasons the IETF has been pushing "try IPv6 first"
as there will likely be no speed difference and it requires application
bias to be able to see when you can turn off the expensive IPv4
kludges. If you selected the destination address family just on
speed you would end up with a roughly 50/50 mix.
