+Tuning Recommendations
+======================
+
+The following is an example of /opt/tomcat/bin/setenv.sh that has been tested on a multi core server running under HTTPS load test requests.
+This is following the general recommendation to use the G1 garbage collector for JVM applications running on multi core machines.
+In addition to using the G1 garbage collector the InitiatingHeapOccupancyPercent was lowered to run garbage collection more frequently which
+improved overall throughput for Traffic Router and reduced 'Stop the World' garbage collection. Note that setting the min and max heap settings
+in setenv.sh will override init scripts in /etc/init.d/tomcat.
+
+ /opt/tomcat/bin/setenv.sh::

+ #! /bin/sh
+ export CATALINA_OPTS="$CATALINA_OPTS -server"
+ export CATALINA_OPTS="$CATALINA_OPTS -Xms2g -Xmx2g"
+ export CATALINA_OPTS="$CATALINA_OPTS -XX:+UseG1GC"
+ export CATALINA_OPTS="$CATALINA_OPTS -XX:+UnlockExperimentalVMOptions"
