A Technology Preview of Nginx Support for QUIC and HTTP/3
Question to ones following quic/http3 development, what does it bring over http2?From my point of view, http3 is more of a sidegrade and has no net benefit over http2.We can make TCP fast, very fast, and the use of UDP was not a prerequisite for any of its functionality.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.By throwing away TCP, they are throwing away decades of optimisations, and hardware offloading that network hardware makers made to handle TCP well.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.
