I managed a system that really benefitted from Rieser. Reiserfs's idea of a "small file" was 1-2 orders of magnitude smaller than most other filesystems, and this system stored map tiles of the entire globe, many, many of which were 37 byte long all blue tiles. Reiserfs stored it in a fraction of what ext or xfs would take. Ideally some meta-tile format would have been used, like with mod_tile, or some deduplication or hard linking, but reiserfs just handled it like a champ.
