> There is an idea that the 14kb rule no longer holds true when using HTTP/2. I've read all I can about this without boring myself to death — but I haven't seen any evidence that servers using HTTP/2 have stopped using TCP slow start beginning with 10 packets. HTTP/3 formally replaces TCP with QUIC.[0] Google have been using QUIC in production for quite a while (since 2013!) and it’s enabled by default in every browser except Safari[1] so it’s understandable how there could be some confusion here.
