This is not something I would have though a few years ago. It is something I learnt after working on many different projects, some using an ORM layer like Hibernate, Entity EJBs, or JDO, some using JDBC approach via Spring Templates or custom frameworks. Many projects that use ORM have performance problems, that don't seem that common with projects using JDBC. But the size of the database model of ORM projects is often much bigger than the one of JDBC projects (which actually makes sense). If you have only a few queries to do, why bother with ORM? This would be complexity for nothing.
