Work in progress.

Simplified and reworked fork of fasthttp.

Intended to serve plaintext HTTP 1.1 behind load balancer and reverse-proxy in controlled environment.

Fully buffers requests and responses.

Non-goals

• Client
• Load balancing
• WebSocket
• Streaming, like io.Reader or io.Writer
• Forms
• Files
• HTTP 2.0, 3.0, QUIC
• TLS
• Running without reverse proxy
• Optimizations for idle connections

Benchmarks

Due to different tradeoffs, direct comparison with net/http and fasthttp is invalid.
