Persistence and mnesia have very little to do with each other. Rabbit
has never used mnesia for storing messages. The "new persister" makes
Rabbit vastly more scalable. It does not change any of the guarantees
made about when messages are written to disk.

That is indeed questionable. You should ensure that the nodename is the
same on both machines to allow mnesia to startup and load the database.

Can you be more specific as to exactly what issues you have run into and
under what circumstances? That way I can suggest what improvements you
will see for each case with the new persister.
