history depth does not matter (on the client side). As for
gentoo-x86's large worktree, using index v4 and avoid full-tree
operations (e.g. "status .", not "status"..) should make all
operations reasonably fast. I plan to make "status" fast even without
path limiting with the help of inotify, but that's not going to be
finished soon. Did I miss anything else?
