spring - Activemq degrade response time -

-

i`m using activemq 5.10 spring 4.1.1. find degrade problem response time of messages. after 4 days, response time starts grow 15ms 200ms , more. app works fine approximately 1000 messages per second , run slower.

here part of xml beans:

<amq:systemusage>             <amq:memoryusage>                 <amq:memoryusage limit="512 mb">                 </amq:memoryusage>             </amq:memoryusage>             <amq:storeusage>                 <amq:storeusage limit="50 mb"></amq:storeusage>             </amq:storeusage>             <amq:tempusage>                 <amq:tempusage limit="50 mb"></amq:tempusage>             </amq:tempusage>     </amq:systemusage>      <amq:broker brokername="mybroker" id="broker"         persistent="false" deleteallmessagesonstartup="true" enablestatistics="false"         useloggingforshutdownerrors="true">          <amq:transportconnectors>             <amq:transportconnector                 uri="nio://${ip}:${port}?jms.useasyncsend=true?jms.usecompression=true"                 disableasyncdispatch="false" />         </amq:transportconnectors>          <amq:destinationpolicy>             <amq:policymap>                 <amq:policyentries>                     <amq:policyentry queue=">" optimizeddispatch="true" />                 </amq:policyentries>             </amq:policymap>             </amq:destinationpolicy>      </amq:broker>      <!-- jms connection factory activemq -->     <bean id="connectionfactory" class="org.apache.activemq.activemqconnectionfactory"         p:brokerurl="nio://${ip}:${port}" />       <bean id="pooledjmsconnectionfactory" class="org.apache.activemq.pool.pooledconnectionfactory"         destroy-method="stop">         <property name="connectionfactory" ref="connectionfactory" />         <property name="maxconnections" value="10" />     </bean>  <bean id="listener" class="xx.com.xxx.messagelistener" /> <jms:listener-container container-type="default"             connection-factory="connectionfactory" acknowledge="auto">             <jms:listener destination="${queuename}"                 ref="sisbusmessagelistener" method="onmessage" />  </jms:listener-container>

and here java code:

public class messagelistener extends genericmessagelistener {      public void onmessage(message request) {         myexecutor mythread = new myexecutor(request, new datetime());         executor.execute(mythread );     } }

public class myexecutor {

public void init() {     try {         connectionfactory = applicationhelper.getbean("connectionfactory");         connectionfactory.setalwayssessionasync(false);         connection = connectionfactory.createconnection();         connection.start();          session = connection.createsession(false, session.auto_acknowledge);     } catch (jmsexception e) {         logs...     } }    public void returnmessage(message request, object responsefromexternalsystem) throws jmsexception {      mapmessage response = session.createmapmessage();     response.setjmscorrelationid(request.getjmscorrelationid());      //code set info on map message here      replyproducer = session.createproducer(request.getjmsreplyto());     replyproducer.setdeliverymode(deliverymode.non_persistent);     replyproducer.send(response);     }    }

the solution re-use connections , sessions creating 1 instanace , creating other instance in cases(errors, desconnections...)
