No, each name in a directory is a link to a file. When the directory is full, you can't create a new link --- i.e. you can't put a new name in the directory. Practically speaking you run into other limitations way before that --- typically you run out of inodes in an inode-based filesystem, or your directory search time becomes excessive if you're using a filesystem that uses linear search. For a given workload it's worth testing different filesystems to find out which is best. They vary enormously depending on the underlying hardware and workload. For highly multithreaded workloads on high performance storage arrays, XFS is often a good choice; for single spindle or single-threaded workloads, ext3 is pretty good in my experience. btrfs looks as if it could perform really well for some workloads, but it's still somewhat unstable --- I think the on-disk format may still need some work. I haven't found a workload where JFS performs well yet, and I haven't done enough benchmarking on ext4 to say anything about it.
