>QPID-4287 Poor performance when a priority queue with a ring queue policy has a large backlog
>Bug 860691 - Poor performance when a priority queue with a ring queue policy has a large backlog
>Bug 996249 - Poor performance when a priority queue with a ring queue policy has a large backlog
>
>*** Reproducer https://bugzilla.redhat.com/attachment.cgi?id=815467 from Bug 996249
>
>Tests on mrg32, release builds. What the reproducer shows is that the time to
>send messages of mixed priority to a priority ring queue goes up steadily as the
>queue gets bigger before the fix. After the fix it remains constant.
>
>Note on the generally low throughput results this test: the reproducer uses the
>default sender capacity of 50, which is too low. You can get MUCH better numbers
>by increasing it to 1000. Which I didn't realise till after I ran all the tests.
