Pure JDBC is actually faster because there is no abstraction on top. IBATIS and Hibernate (I use both) rely on reflection to populate objects and reflection is 2x-10x slower than direct Java access. However, being actually faster (in nano or microseconds) doesn't look much different from a user's perspective. If you have extremely high performance requirements, don't deal with anything that does reflection - do straight SQL over JDBC. Paul __________________________________ Yahoo!
