Well DNS over UDP has better performance characteristics than DoT and

That is not up for discussion.
Yes it is, and efforts to stop other WG participants (particularly
those with collected data) from discussing it are not appropriate.
I don’t know what to say. Are we at the point were we create alternate
facts? If the hardware and the location of the client and server are
identical it is impossible to get more throughput, better latency using
DoT or DoH, then DNS over UDP/53 given two similar written servers. Sure
there are stuff like special chips to enhance that, but if you would do
the same to regular DNS you could increase that even more. For the same
effort it is impossible to get the same throughput and latency simply
because there is more work to do.
Now there are other, more service oriented tests that again measure
something else (mostly network latency and cache behaviour), where stuff
is up for discussion, but for the performance case I described, which
matters to people who have to buy and operate these servers, I don’t
see how we can get the same bang for the buck for DoT/DoH.
So long
