I just realized this is awesome news actually. At the moment, the code is aways waiting for the callback before going to the next one: Every call to storeManager.persistMessage will only return when the callback is returned, or the message is persisted on disk. If this is performing as fast as noSync already.. this is great. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4149458#...
