Hey, IIRC, JFS is/was more well known for dealing with large files, similar to XFS. You may have been thinking of reiserfs. It is great for lots of small files as it has a feature is called 'tail packing'[1]. Files under the block size are stored directly in the name tree. For files larger than this the 'tail' of the file is stored in the tree. E.g. for a 4KB block size, a 9KB file would use 2 blocks and the remainder would be stored in the tree. This can cause an extra seek when reading a file, but is often covered by read-ahead and/or ncq when reading more than a single file. You can mount with `-o notail` to turn it off. cheers, Owen.
