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,,,
