----------------------------------
Summary: Improve performance of pull consumers
Key: AMQ-4758
URL: https://issues.apache.org/jira/browse/AMQ-4758
Project: ActiveMQ
Issue Type: Improvement
Affects Versions: 5.8.0
Reporter: Dejan Bosanac
Assignee: Dejan Bosanac
Fix For: 5.9.0
When we have a queue with only pull consumers (prefetch 0), there are a lot of
necessary work being done trying to dispatch every paged message to every
consumer. The problem is that most of consumers are full all the time and we
lose a lot of cpu time trying to traverse all messages. The problem is more
apparent with large number of paged messages.
