Why does repo.git.log() spend so much time?

[Vergissmeinicht]

from git import Repo
repo = Repo('my-git-repo-path')
commit_msg = repo.git.log('some-file-path')
I measure the time spent and it seems that it may take up to 0.3s to get a commit message of some file. I am wondering how the function log() is implemented and how to modify my code to make it faster.
So much thanks if someone can help!

I labeled this issue 'Q&A' because there is no indication this is believed to be a performance regression. Also I will close the issue, as answers are possible with on a closed issue as well.

In the meantime, I suggest to provide much more information about your setup, namely the operating system, python and GitPython version, as well as the kind of file-system the repository is located on. Maybe it's useful to also provide numbers of the similar functionality produced by the git command-line program, both on cold and hot file-system cache.

It might be worth for you to produce a script that reproduces the issue on any machine, and pass it through a profiler. Good luck.
