I work on a project using EJB 2.0. We have about 50-60 entity beans, and we use the session bean facade pattern. We do a bench (about 100 users) on this project, and I tried to see how the ejb container parameters influence the performances. So, I put the commit-option on A and I sized the cache to: min-capacity = 10 max-capacity=200
Disaster!! The performances degraded after only 30 users.
