>So the fairer comparison might be TLS 1.3 under all three, but if you need to upgrade why not upgrade the whole HTTP stack? Because it's a benchmark of HTTP3 and not a comparison of "as it might be stacks". It would a bit like bench-marking HTTP/1 with RHEL7 and Apache2, HTTP/2 with RHEL8 and NGINX and HTTP/3 with...let's say Alpine and Caddy...it's just not a clean benchmark if you mix more then one component and try to proof that this single one component is faster.
