C++ the Clear Winner In Google's Language Performance Tests

Paul Dubuc writes "Google has released a research paper (PDF) that suggests C++ is the best-performing language on the market. It's not for everyone, though. They write, '...it also required the most extensive tuning efforts, many of which were done at a level of sophistication that would not be available to the average programmer.'"

That's because Java floats are not the same as C floats so compiler can't use the CPU's FPU to do the work for it directly. Java float types make more wider guarantees than C floats (that are usually just restricted to underlying hardware float). This is exactly the reason why Fortran beats C or C++ when it comes to numerical computation. The Fortran compiler can output faster code because language makes some guarantees and it's easier/possible to optimize it better.
