I'm not sure this is as true as it used to be, especially if you're using ext3 with dir_index enabled. Still, XFS is highly optimized for large files/directories, and my empirical experience is that it is the best overall filesystem unless one has special considerations such as full-data journaling or RAM/CPU constraints. > However, I read that reiserfs was more efficient than ext3 handling > lots of small files, which sounds like a good choice for this ReiserFS is more efficient at handling small files because of tail-packing, but you sometimes pay for that space efficiency with speed as reiserfs3 does a lot of continuous shuffling of its hash tree. I've also found reiserfs3 to be less reliable on my systems when compared to XFS.
