Well also the documentation for that is really sparse. Years ago I messed around a lot with JRuby and I found this Xmx flag. So every time I had out of memory problems after, tuning Xmx worked just fine. ;) I always wondered why it's such a "hidden" parameter... Of course Go and Ruby work out of the box. On the other hand, their runtimes are kind of lightweight and less general purpose as the JVM.
