  8. mitata

    benchmark tooling that loves you ā¤ļø

    Project mention: Show HN: Made a small JavaScript benchmarking app – BenchJS | news.ycombinator.com | 2025-01-02

    Mostly I want to benchmark code in our production monorepo, so a web tool doesn’t make much sense. We have a bunch of data structure code and standard utility libraries so it’s not feasible to copy everything into a web form.

    When doing data structure work I’ve started writing micro benchmark files with mitata (https://github.com/evanwashere/mitata) which does a decent job running GC between runs and outputs some very cute graphs and such. I recently rewrote a core container class we use at Notion and for a 5% speed up on a bunch of our public API routes.

    OP, I see you have a mitata-inspired benchmark library ā€œbenchmateā€, I’m curious about difference from mitata, what was missing from it, features added? I looked a bit at the code and it’s certainly easier to read… mitata codebase feels like C written by someone who’s too smart.
