For better performances use VM cursor and small memory limit.
For more information, see:
http://activemq.apache.org/message-cursors.html
Also, if your producer is "hanging", it's probably due to producer flow control.

The managementContext is used to configure how ActiveMQ is exposed in
JMX. By default, ActiveMQ uses the MBean server that is started by
the JVM. For more information, see:
http://activemq.apache.org/jmx.html
-->
<managementContext>
<managementContext createConnector="false"/>

<!--
Configure message persistence for the broker. The default persistence
mechanism is the KahaDB store (identified by the kahaDB tag).
For more information, see:
http://activemq.apache.org/persistence.html
-->
<persistenceAdapter>
<kahaDB directory="${activemq.data}/kahadb"/>

<!--
The systemUsage controls the maximum amount of space the broker will
use before slowing down producers. For more information, see:
http://activemq.apache.org/producer-flow-control.html
If using ActiveMQ embedded - the following limits could safely be used:
<systemUsage>
<systemUsage>
<memoryUsage>
<memoryUsage limit="20 mb"/>
</memoryUsage>
<storeUsage>
<storeUsage limit="1 gb"/>
</storeUsage>
<tempUsage>
<tempUsage limit="100 mb"/>

The transport connectors expose ActiveMQ over a given protocol to
clients and other brokers. For more information, see:
http://activemq.apache.org/configuring-transports.html

<transportConnectors>
<!-- DOS protection, limit concurrent connections to 1000 and frame size to 100MB -->

启动方式:
cd /home/apache-activemq-5.8.0/bin/linux-x86-64/
./activemq start
./activemq stop
发送端相关代码.
connection只要程序启动创建一次就可以了,以后都直接创建session来具体操作.
如果一次只提交一条消息,则最好不要开启事务功能.性能会有很大影响.经测试TPS会有10倍的下降.

接收端:
同样,只在程序启动时创建一个connection.创建多个session则会有多个线程接收.

性能测试,可以达到2000TPS的消息推送量,性能和稳定性还是有可靠的.
