Bootstrapping the Web with Scala Native
summary
Builds a Scala Native CGI app, packages it with multistage Docker builds, and scores concrete performance: simple CGI averages ~40 ms under light load, 99th percentile exceeds 1 s at ~150 users and tops near 400 req/s, while a Python CGI hits ~136 ms. Replacing CGI with FastCGI plus a tiny Go proxy drops median latency to ~4 ms and peaks ~1,500 req/s. Adding a libuv binding and multiplexed I/O reaches 4166 req/s with median ~56 ms, showing the approach works.
