<!--  
    Use Stomp protocol
    
    For better behavior under heavy usage, be sure to:
    
    1. Give broker enough memory 
    2. Disable dedicated task runner
    
    e.g. ACTIVEMQ_OPTS="-Xmx1024M -Dorg.apache.activemq.UseDedicatedTaskRunner=false"
    
    To run ActiveMQ with this configuration add xbean:conf/activemq-stomp.xml to your command
    e.g. $ bin/activemq console xbean:conf/activemq-stomp.xml
