Yes. I think most distros still default to nonhashed directories, but for
any large-directory case you really want to turn on hashing.
I forget the exact details, it's somethng like
tune2fs -O dir_index
or something to turn it on (if I remember correctly, that will only affect
any directories then created after that, but you can effect that by just
doing a "git repack -a -d" which will remove all old object directories,
and now subsequent directories will be done with indexing on).
Personally, I just ended up using packs extensively, so I think I'm still
running without indexing on all my machines ;)
