We have a number of broker-networks with static bridges in between. We are 
experiencing bad performance, and loosing messages. Jvm -Xms1024M -Xmx1024M, 
queue memorylimit 64Mb, producerflowcontrol true. 500 Messages of 200 bytes are 
posted by a Stomp-client to only one node at a rate of 200 msg/sec.  
Interesting enough, exactly 75% is lost. Decreasing the rate or message size 
hardly influences the results.

Please advise...

The typical config of all nodes (with a different uri for each 
network-of-brokers) is:

 <transportConnector name="openwire" 
uri="ssl://0.0.0.0:61616?jms.prefetchPolicy.queuePrefetch=4000" 
updateClusterClients="true" rebalanceClusterClients="true" 
updateClusterClientsOnRemove="true"/>

    <networkConnector name="BrokerLinkPmq101ToOmq" userName="system" 
password="${activemq.password}" 
uri="static:(failover:(ssl://omq101-front:61616,ssl://omq401-front:61616)?randomize=false&amp;priorityBackup=true)"
  conduitSubscriptions="false" decreaseNetworkConsumerPriority="true" 
duplex="true" networkTTL="10" prefetchSize="4000" staticBridge="true" 
suppressDuplicateQueueSubscriptions="true" >
       <staticallyIncludedDestinations>
       ....
       </staticallyIncludedDestinations>
     </networkConnector>

Thanks !
