Infinispan just went GA. Hibernate 3.5 is at a CR. It's getting to be time to try clustering our app using Infinispan and their cache provider for Hibernate.
We have a few machines in the QA lab just waiting for this. I hope our gb switch is fast enough to run an Infinispan cluster. Our app hauls a lot of content, and I noticed that they used Inifiband interconnects (way faster than any ethernet, widely used in high-performance computing) in their benchmarks.
If anyone has already tried Infinispan with Hibernate let me know how it went for you.
