Hello ActiveMQ devs, I don't want to seem picky :( but 1 week has passed and still no feedback on this TCP_NODELAY issue. Finding that "wireFormat.tcpNoDelayEnabled" does not work but "socket.tcpNoDelay" DOES work even if it is not documented, already helped 1 person... see the last comment of Helmut at https://issues.apache.org/activemq/browse/AMQ-1137 .
So, could you please update the documentation at http://activemq.apache.org/tcp-transport-reference.html or http://activemq.apache.org/configuring-wire-formats.html to point out that one should use socket.tcpNoDelay=true to enable TCP_NODELAY in ActiveMQ sockets (i.e. disable Nagle's Algorithm)? Just edit the wiki to add something like... "At the moment wireFormat.tcpNoDelayEnabled=true option does not work, please use socket.tcpNoDelay=true instead" or whatever you want. Also it shouldn't take much time to change the code to accept wireFormat.tcpNoDelay as the documentation actually says... this is just an option parsing / option forwarding problem. If you don't at least document the socket.tcpNoDelay workaround, this can lead people to believe that ActiveMQ performs bad in Linux - because with Windows localhost sockets, this problem doesn't arise, unlike Linux sockets - and people testing ActiveMQ on Linux may be disappointed.
