    A lot of thread with JMS/JCA flow

    Fabio R Newbie

      Hello,

       

      When I had a lot of components in my servicemix.xml and I'm using JMS/JCAFlow the program creates a lot of threads (~2000).

      If I change the flow to SEDA it reduces to ~150 threads.

      It seems that SMX creates queues for all the components, how I can configure SMX or ActiveMQ so I can have less threads been created.

       

      Thank's

      Fabio

          For each component, the JCA flow will allocate a thread pool.  You can safely reduce the amount of threads allocated for each component.  In the servicemix.xml configuration file, use the following snippet:

          You should be able to reduce the number of threads used by the JCA flow this way.

            The tunable variables (corePoolSize, maximumPoolSize, queueSize) for the ServiceMix thread pool are available in the servicemix.properties file.
