Christian, thanks a lot for hints. It's interesting topic. Being impressed by long SQL statements generated by Hibernate and understanding that most of them are not required I decided that I need to try an idea of SFSB as backing bean. 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.
Norman, I'm afraid I need to measure whole project. I realized that there is other potential causes of performance loss. For instance it seems that facelets always compiles inclusions and source components in debug mode. Please take my apologies for not being well-prepared when raising this question. I understand that Seam and EJB3 requires some reasonable overhead. But from my point of view a hundred lines of stack traces doesn't seem reasonable. I understand that interceptors can be less time consumptive in comparison with the others sources of overhead. I believe this is a question of reasonable trade-off.
