Maximum java heap size memory

[anjali_62]

Hi All,

What is the maximum java heap size memory that can be allocated to AEM instance?

::* default JVM options
if not defined CQ_JVM_OPTS set CQ_JVM_OPTS=-Xmx1024m -XX:MaxPermSize=256M -Djava.awt.headless=true

And what is the use of MaxPermSize here ?
