I don't have any comments or figures, but I know that in comparison with
the bundled JNDI or SimpleDB PM of Jackrabbit 1.3, our
PooledJNDIDatabasePersistenceManager just works with MySQL. The
jackrabbit ones don't handle well the connection, so at any time, the
connection can be closed due to inactivity, and then the PM tries to
reconnect but fails and then there are some incoherent datas in MySQL.
But we have both in production, and I would say it is quite slower than
derby when writing, but quicker when reading from DB. So, as there is
more read than write (we display more than we update pages in a web
site), it is a little faster :-)
