I have been absorbing this document: http://labs.jboss.com/file-access/default/members/jbossas/freezone/docs/C..., and was wondering if anyone could quantify the performance hit taken when using HA-JMS with a remote DefaultDS database. I am looking at architecting a solution using HA clustering, with HA-JMS topic as a key component. I would hate to go through all the pains of doing this only to find out the performance is not good.
