It actually really runs slower as is it first an interpreter, and the compiler is yet to be optimized to GCC levels; but is has a great compiler infrastructure that could eventually JIT to faster code (it being a runtime compilation, that has statistics, and Graal being capable of partial evaluation)
I was merely pointing at a hole in your argument: the language of the compiler has absolutely no influence in the quality of it's output (again: the JVM compiles to assembly, not to C++).
A compiler written in brainfuck could write code that is more performant than gcc does.
The language does have an influence on compilation speed, though. But that matter in your argument?
