Performance Tuning for Socko
Published 26 August 2012 by Vibul.
Was googling around when I came across this advice for Netty performance tuning (Socko is build on top of Netty).
Trying using the Java options:
java -server -Xms2048m -Xmx2048m -XX:+UseParallelGC -XX:+AggressiveOpts -XX:+UseFastAccessorMethods
Also, to support a large number of sockets, increase your file descriptors.
