Recommended Java 8 settings

[Felipe Jaekel]

Hi,

I used to run TomEE 1.7.2 with java 7 and the following config:
-Xms1G
-Xmx3G (server has 4G)
-XX:MaxPermSize=1G
-XX:+UseTLAB
-XX:+UseConcMarkSweepGC
-XX:+CMSIncrementalMode
-XX:+CMSClassUnloadingEnabled

I upgraded to Java 8 to use TomEE 7.0.x, so I decided to try different
settings:
-Xmx3G (server has 4G)
-XX:+UseG1GC
-XX:+UseStringDeduplication

Are these good settings? What do you recommend?

Thanks
