improving the performance of the object loading in hibernate
------------------------------------------------------------

                 Key: HHH-4086
                 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-4086
             Project: Hibernate Core
          Issue Type: Task
          Components: query-hql
    Affects Versions: 3.2.3
         Environment: hibernate 3.2.3 ga, oracle
            Reporter: shubha
            Priority: Critical



			_sessions = SessionFactoryUtil.getSessionFactory();
			session = _sessions.openSession();
			Query query = session.getNamedQuery(queryName);
			tx = session.beginTransaction();
			results = query.list();
			System.out.println(results.size());			
			tx.commit();

i am trying to get a collection of objects from query.list(). Even though the SQL generated from hibernate runs very fast in oracle, the O/R mapping in case of hibernate is taking lot of time. To fetch around 15 thousand records it takes 8 to 12 minutes. I am using left join fetch on the query
