2. Re: Multi-Processor machines
cepage Apr 17, 2002 10:48 PM (in response to jsents)I'm not seeing the same behavior. My production app runs on a quad-processor 900MHz Xeon with lots of RAM, Windows 2000, and it scales quite nicely.
That being said, my application is very heavily multi-threaded (lots of MDB's running concurrently), and so I would be pretty surprised if it wasn't able to distribute loads evenly among the four processors.
What does the architecture of your application look like?

3. Re: Multi-Processor machines
jsents Apr 18, 2002 10:37 AM (in response to jsents)We followed the MVC architecture for our fronted end, then through the servlet or a helper class we access the one of about 150 session beans, these session beans then go to our cmp entity beans for data from the database. The session bean do all of our business logic. We have roughly 350 tables that we are hitting.
What did you mean by "lots of MDB's running concurrently"
Do you basically just take your desktop configuration and place that on your server or do you make any changes?
Thanks

4. Re: Multi-Processor machines
erik777 Jun 24, 2002 2:14 PM (in response to jsents)Does anyone know the answer to jsents' question?
I understand that multithreading takes advantage of multiple CPUs. However, does standard Apache HTTP --> Tomcat (JSP) --> Java classes --> EJBs multithread? If so, is it per HTTP request, or can it multithread further? How does JBoss use multithreading?
