I would think that the faster you make both programs, the bigger the
language-dependent speed issue become.

Because first you need to eliminate enormous stalls, if you don't do that,
both have enormous design-related bottlenecks that proportionally dwarf
compiler issues.

I would expect a good C++ compiler (Intel) in the hands of an expert to be
much faster than a good Java compiler in the hands of an expert, perhaps
even 3x, but there might have been massive improvements in the Java
compilers nowadays.
