Performance Tuning Tips

• Turn off diagnostic apps (others as well optional as shouldn't have impact unless used as part of apps) -

      0:Rifidi App: AppService:ReadZones (STARTED);
      1:Rifidi App: AppService:SensorStatus (STARTED);
     2:Rifidi App: AppService:UniqueTagInterval (STARTED);
       3:Rifidi App: AppService:StableSet (STARTED);
  4:Rifidi App: AppService:LimitStableSet (STARTED);
   5:Rifidi App: AppService:UniqueTagBatchInterval (START;
   6:Rifidi App: AppService:RSSI (STARTED);
  7:Rifidi App: Diagnostic:GPIO (STOPPED);
  8:Rifidi App: Diagnostic:Serial (STOPPED);
   9:Rifidi App: Diagnostic:Tags (STARTED);
   10:Rifidi App: Diagnostic:TagGenerator (STARTED);
    11:Rifidi App: Monitoring:ReadZones (STARTED);

     RmiProxyFactoryBean proxy = new RmiProxyFactoryBean();
     proxy.setCacheStub(true);
     proxy.setRefreshStubOnConnectFailure(true);
     proxy.setServiceInterface(SensorManagerService.class);
     proxy.setServiceUrl("rmi://[replace with ipaddress such as 127.0.0.1]:1101/SensorManagerService");
     proxy.setRemoteInvocationFactory(new ContextPropagatingRemoteInvocationFactory());
     proxy.afterPropertiesSet();
     SensorManagerService service = (SensorManagerService) proxy.getObject();
     ReaderDTO reader = service.getReader("LLRP_1");

}

• Consider changing java heap size settings from default 256mb (In eclipse this is limited to 256mb is my understanding)

Esper Performance Tuning Tips - http://esper.codehaus.org/esper-4.9.0/doc/reference/en-US/html/performance.html In particular (20.2.13. Tune or disable delivery order guarantees - if event order is not required by application such as in case of work in progress) - considering option to override in 3.1 easier for user

• Esper Configuration - http://esper.codehaus.org/esper-4.2.0/doc/reference/en/html/configuration.html

Package/class where Rifidi invokes Esper Manager - https://transcends.svn.cloudforge.com/rifidi/rifidi/trunk/org.rifidi.edge/src/org/rifidi/edge/services/EsperManagementServiceImpl.java

• Best practice - when creating custom esper wrap as a rifidi service (looking to make this easier in 3.1) - link to steps on how to config - http://wiki.rifidi.net/index.php?title=How_to_add_a_new_Rifidi_Service

One can disable bundles in bundles.info (caution if not used by app or required by rifidi core) example bundles one can turn off is mysql, aws bundles if not used by an rifidi app
