Actually, I meant that when we used SimpleDBPersistence manager along
with SQLJDBC driver the performance was not that impressive but once we
used the customDBPersistenceManager along with jtds driver and
connection pooling, the performance was impressive.

Any other performance tips?

Thanks & Regards,

that's not correct. there's one jdbc connection per workspace.

having some understanding of jackrabbit's core/internals i dare to
question this claim ;)

anyway, i guess your custom pm is aware of jackrabbit's transactional
requirements
(i.e. all write operations in the jackrabbit commit context *must* use
the same connection)?
