Answer 1

I'd say it depends on your application. If you age going to use a lot of Oracle-related features (like, you need hints in your SQL or hierarchical queries or so on), EclipseLink is more suitable for you. In other case pick up Hibernate. More details you can find at http://simpletoad.blogspot.com/2012/11/what-u-must-know-about-eclipselink-orm.html BTW, don't care about performance benchmarking there ORM - if performance is critial for - don't use ORM at all
