> 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>
