slowest consumer.

URL: https://issues.apache.org/activemq/browse/AMQ-1866
Project: ActiveMQ
Issue Type: Bug
Components: Broker
Affects Versions: 5.1.0
Reporter: Hiram Chirino
Assignee: Hiram Chirino
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.
