[Geoserver-users] Java and geoServer setup optimization under Tomcat

In the past there was a suggestion to add a few options to the tomcat setup, including similar to
-XX:MaxPermSize=512m
-XX:SoftRefLRUPolicyMSPerMB=100000
-XX:+UseParallelGC
-XX:+UseParallelOldGC
-XX:NewRatio=2

Are these still applicable to a current Java (8) and geoServer (2.9) setup? For example, I don't think PermGen memory is used as such anymore. Has anyone tested/benchmarked the system without these? Are there different settings we should be using?

PS. Primary platform of interest for me is Windows.

The current recommendations are available in the user manual; eg. http://docs.geoserver.org/latest/en/user/production/container.html#optimize-your-jvm

On windows you probably want to add the -server option as well

since things change between versions of the jvm and every deployment is different there's no silver bullit; you need to monitor and tweak your server
