hg-git shouldn't be doing anything particular w.r.t. committing. One possible cause is that you have _a_lot_ of draft commits. Try publishing `master` and see if it helps:

$ hg phase -p master

Alternatively, you can enable the `hggit.usephases` configuration setting and pull.

Which version of hg-git, Mercurial and Python are you running?

I regularly use Mercurial with a repository[1] with ~188k commits and a ~44k files in total. I haven't noticed any particular slowness, apart from status and so on — which is to be expected with that many files.
