Hi again, What is the expected behavior with respect to queue message ordering due to priority? I am finding that when I place a higher priority message into a queue, it doesn't get delivered ahead of lower priority messages like I would expect. For example, if I have a producer sending into a queue at 50m/s priority 4, and every five seconds I send one priority 9 message into the queue, I find that an MDB consuming from the queue at 15m/s only processes a priority 9 every few minutes. Once the deluge of low priority messages ends, the queued higher priority messages go through seemingly all at once. I speculated that buffering might be the issue, but SlowConsumers does not seem to help. Are there any other settings that I could tweak? I don't have a test case right now. I am throwing this out there right now in case there are any easy answers, although I'll follow up with a test case if necessary once I have time.
