A comprehensive micro-benchmark compares 15 HTTP server implementations across multiple languages, revealing Scheme (pico + io_uring) achieving 222k req/s and ranking fifth overall. While Rust (axum) leads in throughput and latency, Scheme demonstrates impressive p99 latency of 1.39ms at 256 connections - significantly better than Node.js and Python. The author emphasizes these are synthetic tests measuring raw socket performance rather than real-world application scenarios.
Background
Micro-benchmarks are commonly used to compare programming language performance, but they often focus on synthetic workloads that don't reflect real-world application complexity. HTTP server benchmarks specifically test how efficiently different runtimes handle network I/O and concurrency.
