Improve batching of writes for outbound messages.
-------------------------------------------------
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
