Hello,
I have MQ Binding export in my Process Server process which listens on a MQ queue. When a message is put into this queue, MDB doesn't pick it up instantly. A delay of around 4-5 seconds is observed between putting the message and it being picked up my MDB.
Is there any configuration which will reduce rather eliminate this delay?
Thanks in advance

How do you know the message is committed?

External application puts the message into queue. Also I have a loopback in the application. Where the business process triggers itself by putting a message in MQ queue.

My point is - you're sure that the 4-5 second delay is between "when the message is available for GET" and "when the MDB retrieves the message"...
And not, for example "when the sending application *logs* that it did the put" and "when the MDB retrieves the message". Because it could take that 4-5 seconds for the sending application to COMMIT the message. Or the clock on the sending system could be off by 4-5 seconds or etc. etc. etc...
Other than that, yes, there are some "polling" kinds of intervals on the QCF - but I don't remember what they are off the top of my head.
