------------------------------------------------------------------------
I tested with AMQP client and OpenWire client, here there is not difference in
performance between the CLIENT_ACKNOWLEDGE and AUTO_ACKNOWLEDGE with those,
There is something going on in the Artemis core client here, especially as the
perf is much much slower.

>
> Artemis recommendation in docs is to use CLIENT_ACKNOWLEDGE instead of
> AUTO_ACKNOWLEDGE, on perf testing it seems this is not the case.
> On checking code it seems the reason for this is because ActiveMQMessage
> acknowledge actually calls session.commit, causing a full session commit all
> the time.
> On checking Core API, calling message.acknowledge it seems to behave as
> expected, as such believe this to be an issue in JMS api wrapper, that it
> should just be delegating to the ClientMessage.acknowledge method and this is
> the cause of the perf issue.
