Hibernate Criteria API vs HQL Overhead

I was wondering what was the framework weight in the performance of my application, and I wanted to check at several frameworks performance. I used JMeter to benchmark a stripped application (database access through tomcat) under various loads.

My very modest test shows no significant difference between Hibernate Criteria API and HQL access for queries. Criteria might be a few milliseconds slower, but my query time will take 10x more time, even for a relatively simple query (my query is has 3 inner joins, is grouped, with a count and takes only 4ms when performed once in mysql under no load).

It seems much more important for the Framework of choice to provide good scalability, easy development and maintenance, rather than saving a few cycles, unless the Framework becomes a bottleneck.
