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!
