[jBoss-Dev] Fw: Set Beans Passivation

[Marco Pappalardo]

Hi all, I'm Sw. Eng. Marco Pappalardo and I'm developing for Ergotech System Inc. a sw using JBoss and InstantDb. I had some troubles about performances and I want to talk to you about them in order to ask you to let me know if you have some suggestion.   I'm using a Celeron 500 processor with 128 Mbyte RAM. Performing my tests, I noticed my application is too slow. I made some tests in order to understand where I lose my time, seen that I use both java classes and Stateful Session + Entity Beans. I had the impression that Session Beans should cause my troubles. So I made some test to have an idea about Session Beans Activation and Loading times. As you can see below, times beetween activation and loading are different but about all are 30 or 40 msecs. Do you think it is a right time for JBoss to access my Database? And what time about creation? What can I do to decrease these times? Do you think I will increase sw performances changing my database?   Activate: 971289019698 Load: 971289019728 ... Activate: 971289020269 Load: 971289020309 .... Activate: 971289036782 Load: 971289036862   Have you any estimate concernig time spent by the container asking for data on database? And beetween Session Beans? And beetween a Session and an Entity Bean? Do you think Should I have a considerable increasing if I put my business Logic directly on Entity Beans and avoiding use of Session Beans?   Is there a way to find out spent time executing my code and one spent by the container?   I also tried to disable console logging in JBoss configuration but performances increased too few to be considered!!   I thank you in advance for what you'll do to help me.
