Impressive writing about Hibernate Cache

I don’t usually post great links, but this one is truly impressive.

Hibernate comes with three different caching mechanisms – first level, second level and query cache. Truly understanding how the Hibernate caches work and interact with each other is important when you need to increase performance – just enabling caching in your entity with an annotation (or in classic .hbm.xml mapping file) is easy. But understanding what and how things happens behind the scenes is not. You might even end up with a less performing system if you do not know what you are doing.
