Andrew Stitcher 2013-04-17 22:58:15 UTC Doc Text Feature:
By Default the qpid C++ clients and broker now turn the Nagle algorithm off (this algorithm improves bandwidth of connections by sacrificing some latency)

Reason:
Under most circumstances using qpid you get better or identical performance with the Nagle algorithm turned off.

(Where this is not the case the algorithm may be turn back on again using --tcp-nodelay=no on the command line for the broker or tcp_nodelay=no in the configuration file)

Result (if any):
There should be a performance improvement for most users configurations.

The qpid C++ clients and broker now deactivate the Nagle algorithm by default. The Nagle algorithm improves the connection bandwidth by sacrificing some latency. Under most circumstances, using qpid will achieve identical or improved performance with the Nagle algorithm deactivated. Where this is not the case, the algorithm can be enabled by specifying the `--tcp-nodelay=no` option on the command line for the broker, or `tcp_nodelay=no` in the configuration file. This enhancement should result in a performance improvement for most user configurations.
