## Additional context

The issue concerns lag while loading a git repository when git is not installed, but it provides no files, logs, or reproduction steps. Start by reproducing the situation without git installed and tracing the repository-loading entry point. Done means the repository loads without the reported lag and the behavior is covered by a relevant test, if one exists.
