Hi,
Yes we measure that with top command. And when we try to decrease especially
MaxPermSize value it stalls if we use ConcMarkSweepGC or gives PermGenSpace
with serial gc. We are stuck at this moment because we are unable to start
base glassfish with 3 listeners (jk + normal + ssl) around 100mb and when we
deploy our applications without any access it hits to 200mb and when people
start to use it, GFv3 hits to 250-300mb in memory consumption. These values
are very high for our production environment and we are unable optimize
them.
Do you have any optimized domain.xml for latest nightly builds?
Thanks again..
