I don't know if there is a true limit, but many filesystem types fall down performance wise well before they hit true limits. For instance, with NTFS I've seen 3 1/2 million files in one directory, so in theory it works. But at about 10,000 files, the performance starts to drop. At 3 1/2 million files it took forever to work with the files in that directory. Reiserfs in that situation runs fine :-p
As does current ext3 and ext4. Although in any case [using any
filesystem] NSS can still kill your performance depending on how you are
stating the directory.
