Not being limited does not mean it is a good idea to go huge. It is
still a database made up of 32KB slots. They are just able to be chained
in sequence now to store objects bigger than 32KB (one single slot).

There are still issues around the mime headers portion needing to be
fully within the first slot, the fact that the DB is loaded in MB
chunks, and sequentially walking the lists of slots an object takes up.

Can you try an experiment?
 breaking that very big rock dir into a few with different object size
ranges in each.
