Apparently Java has two types of switches, the green and native switch. The
native can only use one kernel thread which essentially mean one CPU.

Totally see why I sound lost. I possibly don't what I am taking about but I
have checked cacti graphs at work and all seem to max up on one CPU.

Google a bit and you will see a lot of people having that problem.  Java
can use multiple CPU together for garbage collection but the application
side, its only one CPU as far as I can tell
