> Key: QPID-3841
> URL: https://issues.apache.org/jira/browse/QPID-3841
> Project: Qpid
> Issue Type: Improvement
> Components: C++ Broker
> Affects Versions: 0.15
> Reporter: Ken Giusti

> Priority: Minor
> Fix For: 0.15

> 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
