I have read that very big messages if parsed in WBIMB can degrade performance. My questions:
1. Is this applicable only when parsing the messages using message set (I don't think so)?
2. What is the optimal size of a message that can be processed with in a flow?
Thanks very much |

Where did you read this? Maybe it has more information than just that!

Larger data structures typically require more time to process.

It depends.
There are support packs that discuss WBIMB performance in various situations. If you have questions, that is a good place to start.

Navigating the message tree in WMQI can take exponential time the larger it gets. There are ways to code around this. It's not a short subject.
The number of fields/elements matters more than the size of message in this sense.
I would keep messages below 1 mb and less than 1000 elements to avoid problems. This is a performance suggestion, not a limitation. |

Jeff,
Can you please let me know where I can find those resources?
Thanks,

Always a good place to start is: http://www.ibm.com/mqseries, then if you select "Support", that page contains a link to all the SupportPacs.
Cheers,
