incredibly slow. That and the matter of having 44000 files to process with that slow stat().

If that is core.ignoreState you mean, than maybe this is what I mean. I haven't tried it yet (now I wonder myself why I haven't tried it). But (I'm repeating myself, in <81b0412b0612060235l5d5f93d0hd1aaf34924f7783@mail.gmail.com>) I do not really understand how it _can_ help: "I ask because it does not ignore stat info, as the name implies. Because if it would, there'd be no point of calling lstat at all, wouldn't it?" That last question was about refresh_cache_entry - it calls lstat unconditionally.

Still, I guess I'll have to try it.

But aside from me trying ignoreState, can anyone help me with that question regarding checking if the index is any different from HEAD? Because even on a very brocken filesystem and 40k files in a repo you sometimes do want to call git-update-index --refresh just to be sure you haven't missed anything. And than it'll quickly become annoying flicking ignoreState back and forth.
