🚀 New challenge type: Server Competitions! Until now you’ve optimized programs - now you optimize whole servers. Our first one is live: Auth Server. Build an HTTP authentication server, package it as a Docker image, and docker push it to our registry - every push is automatically benchmarked against a freshly generated, hidden dataset, so there’s nothing to overfit. Lowest total request time wins. Grab the API spec and climb the leaderboard!
🎉5 years of HighLoad.Fun!🎉 Half a decade ago, the domain was registered - and what started as an idea has grown into a community of engineers obsessed with squeezing every last nanosecond out of their code. Thanks for being here.
