[jboss-user] [Performance Tuning] - Re: High System CPU Time

Two suggestions. 1) Set -Xms and -Xmx to the same size - this prevents the JVM from asking the OS for more memory, which can case the system time to go up. 2) Set the NewSize to 1/3 or 1/4 of your heap size. With a heap of 512MB, set -XX:newSize=150MB and -XX:MaxNewSize=150MB. If the server is dedicated to running the application server, I would set heap to 1200MB and NewSize to 300MB. Those are usually good starting numbers for a system that has 2GB RAM. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4091194#...
