I annotated all the relations among entities as fetch=lazy. So all the requests that are generated during page rendering are single select without joins. Tree-related requests are generated only when expanding a node. Thus I don't think that Hibernate or DB is the cause. Of course it is the cause. Enable the SQL log and count the number of queries. You are just guessing here. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4008208#...
