Keith Wall created QPID-7963: -------------------------------- Summary: [AMQP1.0] Transient messages traverse the heap (even those that don't flow to disk) Key: QPID-7963 URL: https://issues.apache.org/jira/browse/QPID-7963 Project: Qpid Issue Type: Bug Components: Java Broker Affects Versions: qpid-java-broker-7.0.0 Reporter: Keith Wall
Examine heap usage whilst running a large transient message test, I see that large AMQP 1.0 messages manifest fully on the heap whilst they traverse the Broker. Neither AMQP 0-9 not AMQP 0-10 do this. See attached jvisualvm screenshot. The spike at 3.17PM is a 300MB message being produced/consumed. Later in the same test (same graph) a 750MB message went over AMQP 0-9 and 0-10 messages with no discernible heap impact. -- This message was sent by Atlassian JIRA (v6.4.14#64029) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@qpid.apache.org For additional commands, e-mail: dev-h...@qpid.apache.org
