    Speeding up messages through ESB

    Alexander Lengson Newbie

      Hi all,

      I am novice at ESB, trying to get in now.
      I tried out 'load_generator' sample and found out that the time when message sits in the bus grows up to 30 secs (using the deafult settings from load_generator). Discovered this by adding the creation time to the message as a property and later comparing it to the time when message arrives to the service. Grows from 15ms for first messages up to 30 sec for last one.
      I wonder if there are any ways to speed up message's pushing through the bus.

      Can I turn off persistance to get lightweighter ESB?
      Is there any other services that could be turned off to get the higher performance, even loosing some functionality?

      Thank you,
      Alex

          Hello,

          can you show me your jboss-esb.xml here (at least some "important" parts)? You can use jms-jca-provider and have the queues served by more threads for instance. But it depends on the content/intent of your ESB deployment.

            Martin,

            This is the default jboss-esb.xml from load_generator:

            I tried to increase ThreadsCount from 1 up to 10.That decreased the delay three times.
            But that is still not enough.
            Can I disable Hypersonic (Hibernate) for the bus? I just can not find a mention about that anywhere in the documentation...

            I guess it'll drastically improve the time when the message lays in the bus as it won't have to be serialized/deserialized.

            Thanks.
