Anyway, the maximum number of files in a directory (dirs are just special files) is dependant on the filesystem you are using. I cannot provide any numbers, but for every current FS the maximum should be too high to reach under any but the most unusual circumstances.

Performance might be an issue. AFAIK xfs and ReiserFS are known to be better than ext[23] in this regard (but they may not be as well tested as the standard filesystem. > Is this the right place to be asking this kind of question?
