[opencms-dev] Question about best configuration JAVA_OPTS for OpenCms in production

[Deiverson Silveira]

Hi list,

I wonder what the best configuration JAVA_OPTS do you recommend for use the
application server to the environment production in OpenCms.

I have tested several, and I'm currently using basic this:
set JAVA_OPTS=%JAVA_OPTS%  -Xmx512m -Xms512m -Xmn256m -Xss128k
-XX:+UseParallelGC -XX:ParallelGCThreads=20
-XX:MaxPermSize=512m -Dsun.rmi.dgc.client.gcInterval=3600000
-Dsun.rmi.dgc.server.gcInterval=3600000
or this?
-Xmx3550m -Xms3550m -Xmn2g -Xss128k -XX:ParallelGCThreads=20
-XX:+UseConcMarkSweepGC -XX:+UseParNewGC -XX:SurvivorRatio=8
-XX:TargetSurvivorRatio=90 -XX:MaxTenuringThreshold=31 -XX:+AggressiveOpts

I am trying to understand the settings that best fit the characteristics of
the type of project webportal with OpenCms, find default for projects:
