Ways to improve git status performance

To be more precise, git depends on the efficiency of the lstat(2) system call, so tweaking your client’s “attribute cache timeout” might do the trick.

The manual for git-update-index — essentially a manual mode for git-status — describes what you can do to alleviate this, by using the --assume-unchanged flag to suppress its normal behavior and manually update the paths that you have changed. You might even program your editor to unset this flag every time you save a file.

The alternative, as you suggest, is to reduce the size of your checkout (the size of the packfiles doesn’t really come into play here). The options are a sparse checkout, submodules, or Google’s repo tool.

(There’s a mailing list thread about using Git with NFS, but it doesn’t answer many questions.)
