XX:MaxPermSize max value in 32bit

Question

Can someone confirm that for a 32bit system:

Is there any disadvantage in using the below settings:

-Xms1024m -Xmx1024m -XX:PermSize=768m -XX:MaxPermSize=768m

(We need higher perm size because of excess non heap usage which is some design flaw which shall be corrected later...)

Answer 1

I don't see why there would be any disadvantage, it's a simple configuration, you can do what you want.

This configuration will depend on the amount of physical memory you can use as a maximum and how much you really need.

Also remember, it's a max size, you might never reach it.
