Hi,
This is issue with NFS file system only .
We had the similar experience where we found Queue Manager server in one DC and NFS in another DC.
Now coming to your issue you need to reach your storage system about this latency these latency usually observed in ORACLE NFS but not on NetApps.
In your case it is AWS EC2 with EFS where we did not had this type of environment.

Subject: IBM MQ 9.3 in AWS with EFS as storage - Delay in writing message to queue with Multi instance Queue manager setup.
Hi All,
We have set up IBM MQ 9.3 in AWS EC2 with EFS (NFS 4.1) as the shared file system. We have configured it as a multi-instance queue manager for high availability.
When we start the queue manager as a multi-instance queue manager using the "strmqm -x QMGRNAME" command, we observe a delay/latency when data is written to MQ. It takes 20 minutes for 60K messages to be placed in the MQ with the multi-instance queue manager.
However, when the same queue manager is started using "strmqm QMGRNAME" without the multi-instance setup, we do not observe this delay/latency while writing data to MQ. It takes less than 3 minutes for 60K messages to be placed in the MQ without the multi-instance queue manager.
Can anyone help us understand why there is such a significant delay when using the multi-instance setup and suggest any possible solutions to resolve this issue?
