In above tune the JVM link, it only talks to set xmx and xms and explicitely mentions to not add any other configuration settings.
I am using host with 60G memory and by default the New size value is very small. If i set xms to 16 and xmx 32, will it be enough or do i need to set newsize, survivor ratio, permsize, etc. explicitely? Also, it does not talk anything about default GC config. Do they need to be added? I am using tomcat 9/jdk11 to deploy my app.
