fib

Experimental · Go · standard configuration · completeness 2/4

fib (Fast In Balance) Go networking library: one edge-triggered epoll event loop feeding a logical worker pool, where each connection is an ordered task that any idle worker may run. Its http package serves HTTP/1.1, HTTP/2 (ALPN and prior-knowledge h2c) and, through package http3, HTTP/3 over its own QUIC, all through one handler taking a *http.Request and a Context; TLS through package tls on crypto/tls. Default configuration throughout; the certificate on the opt-in TLS hardening listener is picked per handshake through tls.Config.GetCertificate, so a renewed pair is served without a restart. Handlers dispatch on the path themselves; the JSON routes sit behind fib's compress middleware (middleware.Chain with compress.New(), defaults), which gzips per request as Accept-Encoding allows. /delay and /async-db answer retained requests from a timer and a goroutine, and /static goes through net/http's ServeContent on the Context, choosing the pre-compressed twin on disk off Accept-Encoding.

Achievements

🥇 1 Gold · 🥈 2 Silver · 🥉 5 Bronze. Top three of a field, taken in this entry's own league: the family composite, the same composite among entries written in the same language, and each test profile it is scored on. Every field is the one the badges publish, so a medal and a badge always say the same thing. How medals are awarded.

Composite rank

Each profile of a family is worth 100 to the entry that leads it, and the composite is the sum over the family, less 2.5% for each of routing, middleware, request and response the entry does not do for you - its completeness factor, which the WebSocket and gRPC families do not carry. The field is this entry's own league: engines and reverse proxies are scored apart from frameworks. How it works.

Every result

Alpha Round, 32 runs. Requests per second is the best of three; latency, CPU and memory come from that run.
