[jboss-user] [EJB 3.0] - Re: slow remote communication

[justkeys]

I was able to skip this useless processing of cascades, by clearing the session (entitymanager.clear()) before returning. 

Using trace logging, i found out that the 9 seconds were all used to handle about 400 entities. Hibernate, i think you got a little problem here. Note: with trace logging enabled it took over 2 minutes.
