[jboss-jira] [JBoss JIRA] Updated: (JBAOP-378) Repeated instantiation of pojo with per_instance aspects is slow with generated advisors

[Kabir Khan (JIRA)]

     [ http://jira.jboss.com/jira/browse/JBAOP-378?page=all ]

Kabir Khan updated JBAOP-378:
-----------------------------

            Fix Version/s: 2.0.0.alpha5
    JBoss Forum Reference: http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4031020#4031020
              Description: 
<interceptor name="Int1" class="org.jboss.test.aop.stress.perinstancemethodinvocation.PerInstanceInterceptor" scope="PER_INSTANCE"/>

   <bind pointcut="execution(* org.jboss.test.aop.stress.perinstancemethodinvocation.POJO->method1())">
      <interceptor-ref name="Int1"/>
   </bind>


      public void execute(int thread, int loop) throws Exception
      {
         POJO pojo = new POJO();
         pojo.method1();
      }
	
Executing this loads of times is about 20 times slower with GA's than with Classic weaving. This is probably because for each new object, (Just working off memory here) if an object has per_instance aspects we then need to obtain a per_instance domain, populate the domain, redo all the bindings, and generate a unique joinpoint class for every single object. So I think we need to differentiate between cases where we actually have overridden something in the instance domain (i.e. dynamic aop) and where we are basically just inheriting everything from the parent.
