Not really, as far as absolute limits are concerned.  The entire
directory must be smaller than 2 gigabytes.  That being said, unless
you are using a kernel with the new (and somewhat experimental) htree
extensions, there is a performance penalty with bigger directories, so
depending on how often you are accessing or scanning the large
directory, you may be happier if you use a bushier tree and avoid
directories with a huge number of entries.  (i.e., something like
/afs/athena/user/t/y/tytso, /afs/athena/h/a/hartmans, etc.)
