micro-benchmarks don’t tell the whole story
Summary
The article presents a micro-benchmark comparing 15 HTTP server implementations across multiple languages, highlighting Scheme pico + io_uring achieving strong throughput and low latency. It cautions that micro-benchmarks omit production concerns and introduces the concept of transparent async as an advantage, arguing that architectural choices can yield competitive performance. It also discusses what micro-benchmarks fail to capture and why production reality matters for choosing runtimes.
