I just had a thought this afternoon whether "git add" may benefit from parallelism. It's most likely I/O-bound, although I think if we add a bunch of large files, it might become CPU-bound. To generalize, anything that calls hash_sha1_file() might benefit from parallelism. Another candidate may be git-apply. Actually I just want to speed up git-rebase and think git-apply may be the culprit. Or it could be unpack-trees code.. -- Duy
