A single JMS Listener is way too slow
-------------------------------------

                 Key: AMQ-905
                 URL: https://issues.apache.org/activemq/browse/AMQ-905
             Project: ActiveMQ
          Issue Type: Bug
    Affects Versions: 4.0.1
            Reporter: Daniel Aioanei
         Attachments: activemq.xml

I'm using ActiveMQ 4.0.1 with a DerbyDB backend and I have a single JMS listener for a queue with loads of messages. In order to see how many msg/second are processed by a no-op JMS listener, with a single concurrent session, I used the following configuration:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" 
    "http://www.springframework.org/dtd/spring-beans.dtd">

<beans>

  <!-- START SNIPPET: jca -->
  <bean id="jencks" class="org.jencks.JCAContainer">

    <!-- lets use the default configuration of work manager and transaction manager-->
    <property name="bootstrapContext">
      <bean class="org.jencks.factory.BootstrapContextFactoryBean">
        <property name="threadPoolSize" value="200"/>
      </bean>
    </property>


    <!-- the JCA Resource Adapter -->
    <property name="resourceAdapter">
      <bean id="activeMQResourceAdapter" class="org.apache.activemq.ra.ActiveMQResourceAdapter">
        <property name="serverUrl" value="tcp://localhost:61616?wireFormat.cacheEnabled=false&amp;wireFormat.tightEncodingEnabled=false&amp;jms.useAsyncSend=false"/>
      </bean>
    </property>
  </bean>
  <!-- END SNIPPET: jca -->



  <!--

  <!-- START SNIPPET: inbound -->
  
  <bean id="inboundConnectorA" class="org.jencks.JCAConnector">

    <property name="jcaContainer" ref="jencks" />

    <!-- subscription details -->
    <property name="activationSpec">
      <bean class="org.apache.activemq.ra.ActiveMQActivationSpec">
        <property name="destination" value="queue/MyQueue"/>
        <property name="destinationType" value="javax.jms.Queue"/>
        <property name="acknowledgeMode" value="Auto-acknowledge"/>
        <property name="useRAManagedTransaction" value="false"/>
        
		<property name="maximumRedeliveries" value="10"/>
		<property name="initialRedeliveryDelay" value="1000"/>
		<property name="useExponentialBackOff" value="true"/>
		<property name="backOffMultiplier" value="5"/>
		
        <property name="maxSessions" value="1"/>
        <property name="maxMessagesPerSessions" value="1"/>
      </bean>
    </property>

    <property name="ref" value="testOutboundMdp"/>
  </bean>
	<bean id="testOutboundMdp" class="TestOutboundMdp"/>
  
</beans>


The problem is that the consumption speed is 11 msg/second and cpu consumption is about 1-2%. To get almost 100% cpu usage I have to increase threadPoolSize and maximumRedeliveries to 1000 (!) and at that point the consumption speed reaches 142 msg/sec, which is not too impressive either. I'm not sure if it's a Jencks or ActiveMQ issue here.
