A Technology Preview of Nginx Support for QUIC and HTTP/3
Question to ones following quic/http3 development, what does it bring over http2?<p>From my point of view, http3 is more of a sidegrade and has no net benefit over http2.<p>We can make TCP fast, very fast, and the use of UDP was not a prerequisite for any of its functionality.<p>The "multistream" functionality of QUIC is mainly to benefit companies with big, highly loaded CDNs, and kind of obviates the economic point of squeezing multiple virtual streams into a single TCP connection as used in http2.<p>By throwing away TCP, they are throwing away decades of optimisations, and hardware offloading that network hardware makers made to handle TCP well.<p>If the talk was really about extracting single digit improvements from it, I think it would've made more sense to finally put SCTP, and DCCP to good use.
