The Cost Of An "Empty" Transaction--Screencast 📎

Is it worth to disable transaction (with e.g. @TransactionAttribute(TransactionAttributeType.NEVER)) on an EJB method for optimization purposes? Such micro-optimizations increase the complexity, but what is the actual benefit?

In this following screencast a Servlet was deployed with and without involving a UserTransaction and the performance difference was measured with JMeter.

Thanks for watching!
