AEM 6.5 JVM Options and Performance Tuneups

Avatar

Level 1

We are going live to AEM 6.5.4 version in Production and want to check if below JVM options are correct for a production environment please suggest

 

CQ_JVM_OPTS='-server -Xms8192m -Xmx8192m -XX:MaxMetaspaceSize=1024m -XX:+HeapDumpOnOutOfMemoryError -XX:HeapDumpPath=/data/aem/heapdumps -Djava.io.tmpdir=/tmp -Djava.awt.headless=true'

 

And below as per adobe aem documentation here : https://docs.adobe.com/content/help/en/experience-manager-65/deploying/deploying/custom-standalone-i...

 

CQ_JVM_OPTS="${CQ_JVM_OPTS} -XX:+UseParallelGC --add-opens=java.desktop/com.sun.imageio.plugins.jpeg=ALL-UNNAMED --add-opens=java.base/sun.net.www.protocol.jrt=ALL-UNNAMED --add-opens=java.naming/javax.naming.spi=ALL-UNNAMED --add-opens=java.xml/com.sun.org.apache.xerces.internal.dom=ALL-UNNAMED --add-opens=java.base/java.lang=ALL-UNNAMED --add-opens=java.base/jdk.internal.loader=ALL-UNNAMED --add-opens=java.base/java.net=ALL-UNNAMED -Dnashorn.args=--no-deprecation-warning"

 

Also are there any performance tuneups recommendations for AEM 6.5 other than what is mentioned here https://helpx.adobe.com/experience-manager/kb/performance-tuning-tips.html?

Personally I'd also add : 

 

-XX:+PrintGCApplicationStoppedTime -XX:+PrintGCDateStamps -XX:+PrintGCDetails -XX:+PrintGCTimeStamp

 

These will output Java garbage collection statistics to logs. 

Some of the most useful logs when things hit the fan.

 

Allows you to visualize the Java heap state across time.
