High-Performance Java Persistence Newsletter, Issue 46

Imagine having a tool that can automatically detect JPA and Hibernate performance issues. Wouldn’t that be just awesome?

So, enjoy spending your time on the things you love rather than fixing performance issues in your production system on a Saturday night!
