Please provide further information on:
1. What you mean by: '...messaging are reaching the backend with 1m delay'.
This infers queue manger-to-queue manager message transmission, and contradicts the statement: '...there is one queue manager(QM1) between two applications'.
2. What you mean by: '...it is going to backout queue in qmgr'.
Is it a back-out queue, or do you mean the Dead-letter Queue?
You have provided insufficient information to even attempt to help you.

| My guess, and that is all it can be based on your input, is that the putting application is putting the message under syncpoint and not commiting it. |

It is happening in Reply message
suppose there are 2 applications APP1 and APP2
APP2 is giving reply to APP1 via QM1.
it is back-out queue in QM1
so message are reaching the APP1 with delay 1 minute
please let me know if u need more info
Thanks

Are APP1 and APP2 connected to the same queue manager, i.e. QM1?

Does APP1 time out before the reply comes back from APP2?
Is the delay measurably consistent?
If there is no network involved (ie both apps talk to the same local qmgr) then it is most likely an application issue...and again my guess is that you are putting the request message onto the queue under syncpoint and not issuing an MQCMT. |

how could you think that you have supplied enough info for anyone to determine the problem?
why should anyone help you when you have made practically no effort to help yourself? |

Its also worth pointing out that signficant delays (seconds to minutes) in MQ message processing flows are typically 99% due to application operation or design issues, not MQ ! The hard part is identifying where and why the delays occur.
