Pushing 4.7M Commits an Hour

A custom git server built by Corigin achieved 4.79 million pushes per hour to a single repository across 1,408 branches (p50, 322ms) and 27.8 million clones per hour of a NextJS starter template (p50, 220ms), according to benchmarks published by founder Matt Rickard. The server is designed to support the scale of AI agent workflows, where frontier labs like Anthropic, DeepMind, and Cognition run millions of experiments that require fast, parallel git operations. Corigin's new git server implementation and wire protocol are available at corigin.dev.

The winning software teams will throw away orders of magnitude more code than they merge. I ran a benchmark against the custom git server I’m building, 4.79 million pushes per hour to a single repository across 1,408 branches p50, 322ms . 27.8 million clones per hour of a repository containing the NextJS starter template p50, 220ms . 4.79M commits won’t make it to master, but the frontier labs are running that many experiments at scale, and the rest of us will be soon. Anthropic wrote a working C compiler https://www.anthropic.com/engineering/building-c-compiler with a swarm of 2,000 Claude Code sessions coordinating over git Bun’s Rust rewrite https://bun.com/blog/bun-in-rust did 695 commits/hr for two weeks DeepMind’s AlphaCode 2 https://deepmind.google/AlphaCode2 Tech Report.pdf generated 77 million program candidates for 770 submissions in competitive programming. Cognition is running Agentic MapReduce https://devin.ai/blog/agentic-map-reduce over their codebase to scan for security vulnerabilities. Modal can spin up a million sandboxes in seconds https://modal.com/blog/scaling-to-1-million-concurrent-sandboxes-in-seconds , but what’s the point if those sandboxes have nowhere to read or write? GitHub won’t be the place that the work gets recorded. Branches and repositories should not be sacred. Every agent should use them, liberally. Every parallel agent gets a branch. Every agent turn gets snapshotted and stored in git, so you can provably correlate what turns corresponded which changes. That’s exactly what I’m building at Corigin https://corigin.dev . A new git server implementation and wire protocol built from scratch. Distilled down to the essentials that agents need from first principles. Fast, scalable, and easy for agents to use because it’s just git . We benchmarked https://github.com/r2d4/corigin-benchmarks with git clone and git push . You can try it today at corigin.dev http://corigin.dev . Try it with MapReduce skill https://x.com/mattrickard/status/2073111376516759770 I made to run sharded reviews or edits over your codebase. Or use it to run parallel cloud agents.
