Wiki: Performance
Performance
Results from a stress test of gitbay.org (2026-08-25): a server-side import of the Git project's own repository — 82,056 commits, 1,016 refs, 167MB packed — followed by timed requests against every page type. The instance is a single 1 vCPU / 1GB VPS that was concurrently running the CI runner, the mirror worker, and the scheduler.
Summary
The import took 41.5 seconds end to end. Every core page rendered in under a second against the full history; the heaviest operations — blame on a 7,000-line file and full-clone pack generation — cost what git itself costs, and nothing else. Load peaked at 0.42 and memory held near 190MB through the entire run. A full anonymous HTTPS clone of all 82,056 commits completed in 17 seconds and round-tripped with an identical commit count.

Why it holds
gitbay keeps no object database of its own: transports stream through
git upload-pack, object reads go through git cat-file --batch, and
blame, grep, and archives are the git binary doing what it already does
well. The forge's own work — auth, policy, rendering — is milliseconds
around that. Metadata lives in one SQLite file in WAL mode, which at
this scale never appears in a profile.
The practical ceiling on this hardware is concurrent pack generation: full clones of large repositories are CPU-bound in git itself (the 17s clone ran git at ~156% CPU). A busier instance would scale that with cores, not with changes to gitbay.
