Java is fast enough for having legions of kids playing games written in it, and a full OS userspace, it is a matter of implementation, and how much use gets done in JNI, no different than reaching out to CGO or Plan 9 Assembler, while keeping most of the code in Go.

Oh yes, I didn’t mean to knock the language - I also worked on amazing things in Java before I moved to go.

But the runtime of a Go app is, by default, faster than Java and my experiences have shown much, much better performance with the sort of multi-window full screen throughput we need for building a desktop.
