The use of the configuration option factory.setUseAsyncSend(true); won't
have any effect on the send in this case.

Also keep in mind that you will need to wait for all the onComplete
callbacks to receive the ACK from the broker to be sure all your sends
are successful which will lower the performance to something closer to
what you saw with non-async sends.
