you quickly does the consumer process the 1000 msgs and how fast is the network between broker and consumer? What's the size of the msg? Is the consumer session transacted?
In general the broker can prefetch more msgs to your consumer once the consumer has acked a few msgs. So the broker should try to keep the consumers prefetch full (assuming there are more msgs on the queue to dispatch). The broker generally does not wait for all the 1000 msgs to be acked, before dispatching more msgs. Torsten Mielke [email protected] [email protected]
