Do you use em.Find() or a query to load your objects? You could add the following attributes to your persistance.xml to see whats going on: | <property name="hibernate.show_sql" value="true"/> | <property name="hibernate.format_sql" value="true"/> | <property name="hibernate.use_sql_comments" value="true"/> | On the other hand, why do you load 1000 single objects within a single transaction? Can't you load them all at once. That should perform much better... View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3959098#...
