  • worker threads: Maximize thread lifetimes and minimize thread creation/destruction cycles.
  • Use a separate timer thread to timeout socket operations
  • my EJB: Use the transient keyword to define fields to avoid having those fields serialized. Examine serialized objects to determine which fields do not need to be serialized for the application to work.
  • Start producer connection (dispatcher) after you start consumer (worker).
  • Control transactions by using separate transactional
    session for transactional messages and non-transactional session for non-transactional messages.
  • Choose non-durable JMS wherever appropriate to avoid persistence overhead.
