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.
