How to tune the ejb3 subsystem in JBoss EAP 6
https://access.redhat.com/knowledge/solutions/319783

Diagnostic Steps

  • If comparing the remote ejb calls:
    • Are the tests running on different application servers such as an older JBoss version? What are the versions being tested?
    • Is the hardware the same for both tests?
    • Is the operating system the same in both tests? What are the operating systems used on the client/server side and versions?
    • Is the JVM the same in both tests?
    • Can you provide a reproducer test that demonstrate the issue for us to test?
    • Have you checked the JVM to see if it needs to be tuned? (For example checking for garbage collection issues)
  • Review the ejb3 subsystem configuration
    • What are the bean-instance-pools configuration set to for max-pool-size ?
    • What is the thread pool max-threads count set to?
    • What are the channel-creation-options set to in the remote configuration section of the ejb3 subsystem?
