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

Repeated instantiation of pojo with per_instance aspects is slow with generated advisors ---------------------------------------------------------------------------------------- Key: JBAOP-378 URL: http://jira.jboss.com/jira/browse/JBAOP-378 Project: JBoss AOP Issue Type: Sub-task Security Level: Public(Everyone can see) Reporter: Kabir Khan Assigned To: Kabir Khan Fix For: 2.0.0.beta <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 40-100 times slower (slower with more bindings/methods in class) 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.
