Useful Tomcat JVM Settings

Dr. Chuck recommends using

JAVA_OPTS='-Xmx512m -Xms512m -XX:PermSize=16m -XX:MaxPermSize=128m -XX:NewSize=128m -XX:+UseConcMarkSweepGC -XX:+UseParNewGC' ; export JAVA_OPTS


See http://www.dr-chuck.com/csev-blog/000222.html.

You can also export these as $CATALINA_OPTS.
