Hello All,
I have messages defined with both MessageID and CorrelationID. If I read the messages by CorrelationID it is very fast(0.1 sec). But if i use MessageID to read, it is very slow (20 to 30 sec's).

1. Any idea why it is happening like this?

My queue size is 30K+ messages. And the message would be deleted every restart.
2. Is it feasible to index the queue?

3. Does MQC.MQGMO_NOWAIT make any difference in performance?

Thanks in Advance,
PS
