 Description  « Hide
If you have a JMS producer sending messages to multiple consumers and you have the cacheLevel set to 3 or higher, eventually all consumers will run as slow as the slowest consumer.
In the attached projects the SA sends messages to a MockOptimizer (JMS consumer) that has two threads. One sleeps for one second and the other sleeps for ten. Initially the thread sleeping for 1 second will consume most of the messages, but towards the end it will start to consume messages every ten seconds as well.

Summary JMS producer caching leads to all consumers running as fast as the slowest consumer. Using small queue prefetch sizes cause all consumers to run as fast as the slowest consumer.
