I should wait to tell you this.. but I can't wait! :-) We are working on JBM2, and on my poor Linux Laptop, using native LibAIO I'm doing 25000 persistent messages / second, on a size of 1K each one, which is pretty much my disk limit. We are now setting up a bigger hardware to do more tests. JBM 2 will rock in performance! :-) Regarding the DLQ, have you configured the DLQ attributes? (MaxDeliveryAttempts, RedeliveryDelay and others things like that?) Default configs at: http://www.jboss.org/file-access/default/members/jbossmessaging/freezone/... Also, look at queue configs at: 6.7.2.1.3. DLQ, 6.7.2.1.4. ExpiryQueue, 6.7.2.1.6. MaxDeliveryAttempts View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4145142#...
