[ https://issues.apache.org/activemq/browse/AMQ-903?page=comments#action_36881 ] Daniel Aioanei commented on AMQ-903: ------------------------------------
Every time I ran my test app, the CPU usage staid on 100% so an artificial sleep-like delay doesn't seem to be involved. > ActivemMQ slows down after a rather small number of messages > ------------------------------------------------------------ > > Key: AMQ-903 > URL: https://issues.apache.org/activemq/browse/AMQ-903 > Project: ActiveMQ > Issue Type: Bug > Affects Versions: 4.0.1 > Reporter: Daniel Aioanei > Attachments: activemq.xml > > > I have activemq with a postgresql backend running as a standalone server, and > a client application that produces persistent messages in 50 threads. Each > time I run my app it pushes as many msg as it can for about 62.5 seconds > after which it quits. Although initially it works fast, every time I run my > app it produces less messages: > enqueue speed 50 threads: msg/second: 334.18333333333334 > second time: msg/second: 194.15 > third time: msg/second: 123.0 > fourth time: msg/second: 58.61666666666667 > fifth time: msg/second: 19.433333333333334 > sixth time: msg/second: 33.81666666666667 > seventh time: msg/second: 11.783333333333333 > eigth time: msg/second: 24.733333333333334 > ninght time: msg/second: 10.883333333333333 > After I ran the above test there seem to be 50241 msg in that queue. > activemq=> select count(1) from activemq_msgs ; > count > ------- > 50241 > (1 row) > activemq=> select count(1) from activemq_acks ; > count > ------- > 0 > (1 row) > Note that I don't have any message consumers active for this test. > Here is the way the client app connects: > <bean id="jmsResourceAdapter" > class="org.apache.activemq.ra.ActiveMQResourceAdapter"> > <property name="serverUrl" > value="tcp://localhost:61616?wireFormat.cacheEnabled=false&wireFormat.tightEncodingEnabled=false" > /> > </bean> -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://issues.apache.org/activemq/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
