In my understanding, the Relstorage version is faster than the FileStorage
when the database has a lot of data.

What would be interesting imho is to evaluate when switching from
FileStorage to RelStorage
is interesting in terms of speed up (packing, zope usage, ..), so I would
know for which customer I would switch to postgres for instance.

Another point is about windows: I would love to see the same benchmarks on
such OS.
