I have only one consumer processing message, from the log, it takes 14 seconds to receive the acknowledge response from server, how can I reduce the time and make it quicker?

I just set below two attributes:

    locator.setBlockOnAcknowledge(true);

    locator.setAckBatchSize(0);

All the other attributes are default, and I'm using Jboss-eap-6.2 as the HornetQ server.
