The following sub-sections explain how the recommended performance tuning values can be set:

...

    • -Xms -   This specifies the initial memory allocation pool for a JVM.
    • -Xmx -   This specifies the maximum memory allocation pool for a JVM.

    • -XX:MaxPermSize -  The permanent space is where the classes, methods, internalized strings, and similar objects used by the VM are stored and never deallocated. This defines the maximum space that will be allocated as permanent space.

      Note

      The default JDK value is assigned to  XX:MaxPermSize from JDK 8 and above. Therefore you need not use the XX:MaxPermSize if you are running WSO2 EMM on JDK 8 and above.
