Hibernate Performance articles

I talked to a friend today, and he is implementing an intranet system with Hibernate. They are having performance issues, even though they are using caching and lazy loading. It’s probably due to a bit of a complicated database model, and they might need to tweak some of the SQL that is generated. I did a google and found some relavant articles:

• Gavin King’s tips
• Things I learned about Hibernate….
• Improving Hibernate’s Performance
• GC and Hibernate

I’ll be intrested to see what he ends up with. I’m convinced it will perform ok with some tweaking, you just have to figure out what to tweak.
