I've never used it on Windows, but yes, when working with hundred of
commits it's quite slow; just refreshing the status buffer takes ages.

Thanks for that; I've looked at magit-libgit.el and it indeed doesn't
appear to provide much of anything yet.  I guess we could drop the
dependency for now and revisit it in the future if/when development
picks up again on the magit/libgit integration.

Thanks,
