Death, Taxes, and HTTP

" summary

Explains concrete costs and fixes: TLS handshake often adds 100–300 ms round trips and session resumption or zero-RTT setup removes them; HTTP/1.1 suffers head‑of‑line blocking so clients open extra costly TLS connections; HTTP/2 adds multiplexing, HPACK header compression, server push and conditional GETs to enable independent caching and many small requests. Shows json gzipped versus protobuf bytes parity, notes okp lacks server push today, and that mashi pre-encodes keys to cut parsing allocations.
