    On the other hand, performance drops approx. O(n^2) as you add entries to the
    directory, depending on your access patterns. I wouldn't put more than 300-500
    entries in a directory, but ~1000 may be OK for you. More than that gets very

    If you really want to have huge directories, you may want to look at reiserfs,
    which uses btrees to index the directories. People have been testing it with
    millions of entries without too much performance degredation.
