If you have plenty of memory the odds of the directory not being in
memory when you fetch the inodes are pretty low IMHO, especially as the
directory will be readahead.

Are you sure its not in fact the time taken to walk directories that is
doing the damage, especially if they are big directories. If so then a
btree directory format makes more sense.
