The anecdotes I've heard are that Storable gets more and more expensive as you have to share bulkier data structures across. And that shared memory really bites, while disk storage is much preferred.

If your structures are complex enough, I've heard it was actually better to use a real database to share things! That is, for some amazingly small number of elements in a hash, it was faster to do a data query to PostgreSQL to fetch the interesting parts through a DBI query than to simply use Storable, write it to disk, read it from disk, and then look at it in Perl. Interesting scaling point. That stuck in my brain because it was counterintuitive at the time, both to the observer, and to me.
