We currently are using named queries contained in the hbm.xml files. There has been discussion to rewrite the methods that call the named queries as CriteriaBuilders. I thought I read awhile ago that named queries had better performance. Is this true? Our named queries are single table lookups with a single (usually) where clause parameter. Do named queries on single tables offer the best performance?

Just wanted to give this one final 'bump' in hopes that some new eyes had insight. Thanks.

I think you can use Criteria, the difference(if it is) it doesn;t matter. Named Queries are for complex sql which it cannot be write using criteria. imho
