Are you accurately accounting for the cost of the extra hard/soft links
your scheme requires? Ie the directories get larger, lookups take
slightly longer, etc. Also access to a given file takes longer, and the
deltas are referring to *other* packed files which *also* take longer to
decompress and access...
How much better does delta-fication do, compared to just packing?
