Description of problem: Sending durable messages via AMQP 1.0 on 1.36.0-9 broker exhibit tragic performance / message throughput of approx 10msgs/s. It is a regression from 1.36.0-6 broker that shows normal message throughput. From tests performed, the broker extremely delays sending message acknowledgments back to the probducer, what causes the tragic performance results. Version-Release number of selected component (if applicable): qpid-cpp-*-1.36.0-9 How reproducible: 100% Steps to Reproduce: rm -rf /var/lib/qpidd/* service qpidd restart qpid-config add queue PerfQueue --durable time qpid-send -a PerfQueue --durable=yes -m 100 --connection-options "{protocol:'amqp1.0'}" Actual results: the qpid-send takes from 6 seconds to 15, with average around 9-10 Expected results: qpid-send to finish within a fraction of second Additional info: - sending transient messages (or to non-durable queue) is fast - sending the messages via AMQP 0-10 is afst as well - using 1.36.0-6 broker (in all the scenarios) is fast as well
I might used invalid config, since the performance depends highly on setting of journal-flush-timeout parameter. journal-flush-timeout=1 journal-flush-timeout=15 journal-flush-timeout=500 shows as bad performance as the value is. While using "1ms" there (or "15ms") shows good performance. (that config is quite confusing since it is backward incompatible as 1.36.0-6 doesnt accept "ms" at all - upgrading qpidd with the same parameter value would bring this problem)
Closing as it works as expected, config error behind the report.
