Speed Demon: A Performance Championship

speeddemon.dev Observed source
Editorial interest 88/100 Selection signal · not a rating of the site

A 72-hour programming contest where competitors optimize fixed tasks and run their code on the same dedicated machine.

Landing page captured for the 2026-09-10 issue.

Field notes

The contest supplies competitors with a fixed task, dataset, and deliberately naive implementation, then builds and runs submissions from their Dockerfiles rather than accepting self-reported benchmarks. Measurements take place on a Helsinki machine identified as an i5-13500 with 12 threads and an 8 GB cap; five runs are serialized, with the fastest and slowest discarded. Track A uses 3.1 million structured log lines, and eligibility for the overall title requires entering at least three tracks.
