>
> A patch created by Gordon Sim will allow the connection to batch up outbound
> messages, resulting in less calls to the socket's write method (as more data
> is passed with each write).
> This results in a small performance improvement. For example, given a broker
> with a single queue (flow control disabled), qpid-send filling it and
> qpid-receive draining it simultaineously with 300 byte messages:
> Pre-patch:
> qpid-send= 77581 msg/sec
> qpid-receive= 77345 msg/sec
> Post-patch:
> qpid-send= 84931 msg/sec
> qpid-receive= 84789 msg/sec
