http://community.jboss.org/message/522886#522886 Author : Arbi Sookazian Profile : http://community.jboss.org/people/asookazian Message: -------------------------------------------------------------- h3. 1) Where is this configured (i.e. which Jboss xml file)? h3. 2) what is the default? *3) what is the recommendation for a clustered Seam/JSF/RichFaces application wrt this?* /*******************************************************************************************************************************************/ h3. Performance note - Call By Value The use of call by value and marshalling is very inefficient. It typically means method invocations take 10 times the cpu. Why? Compare Call By Value with Call By Reference h4. Call By Reference 1. caller does ejb.someMethod() 2. invocation is passed through ejb container 3. container does bean.someMethod() 4. result is returned to the caller h4. Call By Value 1. caller does ejb.someMethod() 2. invocation is marshalled - the parameters are turned into ObjectStream (a byte[]) 3. container with a different classloader unmarshalls - byte[] -> java Objects - including classloading 4. invocation is passed through ejb container 5. container does bean.someMethod() 6. result is marshalled - the return value is turned into ObjectStream 7. result is unmarshalled using the caller's classloader - byte[] -> java Object 8. result is return to the caller The marshalling and unmarshalling uses a lot of cpu. from: http://community.jboss.org/docs/DOC-9288 -------------------------------------------------------------- To reply to this message visit the message page: http://community.jboss.org/message/522886#522886
