It depends on the average queue size and contention of the queue. With many entry a queue runner interval might be exhausted easily and retry streches over multiple intervals. I would regard a 10 to 15 minute queue runner interval as acceptable. If the queue is nearly empty the retry happens 4 to 6 times a hour. That's not very aggressive meanwhile. Our inbound queuerunner operates in permanent queue running mode which could lead to a retry every minute if the queue is nearly empty. This is more or less "aggressive" ...
