Summary: Improve broker's performance by rate limiting queue
cleanup.
Key: QPID-4046
URL: https://issues.apache.org/jira/browse/QPID-4046
Project: Qpid
Issue Type: Improvement
Components: C++ Broker
Affects Versions: 0.16
Reporter: Ken Giusti
Assignee: Ken Giusti
Priority: Trivial
Fix For: 0.17
The cleanup of dequeued messages is done on the receive path with the Queue's
messageLock held (has to be held). When multiple consumers with large ack
windows are sharing the queue, a large backlog of messages can build up.
Performance of the consumer can be improved by rate limiting this queue cleanup.
