Subject Performance compared to official performance statement
Date Tue, 07 Aug 2007 13:49:20 GMT

Hi folks,

i am a little bit surprised about the performance of my broker-network.

The AMQ-Website says:

When running the server on one box and a single producer and consumer thread
in separate VMs on the other box, using a single topic we got around
21-22,000 messages/second using 1-2K messages.

I have almost exactly the same setup:

- one single broker on one machine
- consumer and producer on another

I don't use anything time-consuming, meaning message delivery is set to be:

- non-persistent
- no transactions
- 1k-messages max
- asynchrous
- no failover
- stomp as protocol

Even so my sample-network only achieves a message throughput of approx. 1000
messages per second.

What could be the reason for this?

Here is my broker-config.xml:

<beans>

  <!-- Allows us to use system properties as variables in this configuration
file -->
  <bean
class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"/>

  <broker brokerName="singleBroker" useJmx="true"
xmlns="http://activemq.org/config/1.0">

    <!-- Use the following to configure how ActiveMQ is exposed in JMX -->
    <managementContext>
       <managementContext connectorPort="4444"
jmxDomainName="org.apache.activemq"/>
    </managementContext>


    <!-- In ActiveMQ 4, you can setup destination policies -->
    <destinationPolicy>
      <policyMap><policyEntries>

          <policyEntry topic="ice">
            <dispatchPolicy>
              <strictOrderDispatchPolicy />
            </dispatchPolicy>
            <subscriptionRecoveryPolicy>
              <lastImageSubscriptionRecoveryPolicy />
            </subscriptionRecoveryPolicy>
          </policyEntry>

      </policyEntries></policyMap>
    </destinationPolicy>

    <transportConnectors>
       <transportConnector  name="openwire" uri="tcp://localhost:61616"
discoveryUri="multicast://default"/>
       <transportConnector  name="stomp" uri="stomp://localhost:61613"
discoveryUri="multicast://default" />
    </transportConnectors>

  </broker>


</beans>

My producer and consumer are based on the activemq-cpp example.

tcp://172.18.117.126:61613?wireFormat=stomp&transport.useAsyncSend=true

would be an example URI.

Any ideas?
