Benchmarking git client implementations on real-world repository operations.
6 operations (current branch, status, log (100), tracked files, changed files, read 25 blobs) executed across 5 runners: git CLI, libgit2 via bun:ffi, gitoxide, isomorphic-git, and ziggit.
The target is a full clone of vercel/next.js. Each operation is timed across multiple samples; the median is reported.
