I'm curious as to what the performance problem is and why distributing the problem would make it perform better.

Things to consider. A tuned WebObjects instance can serve hundreds, maybe even one-two thousand concurrent users. But that assumes a distributed environment with 5-10 webservers machines, 2-3 WebObjects app servers machines, and a decent RDBMS machine. Would that count as a distributed environment?

The previous is from experience. One of my VPs went on Good Morning America and talked up our portal without telling us. A few thousand users showed up and our system sustained the load but response time was poor.

Ray,

what exactly do you mean by "generates a lot of instances from a java-class"?

WebObjects does load balancing by having several instances of one and the same application running on one or more servers. Once a user has a session with one instance of the application s/he will be served by that instance.

Other products use distributed objects to balance the load. That is not something WebObjects does on its own. You might want to use Corba or enterprise JavaBeans for that.

You may also partition your business and have several distinct applications running: client interface, admin interface, batch computation,,,
