Re:Why Java still isn't faster than C++ (Score 1)

Did you try reading any of the rebuttals helpfully provided by the site (the links at the bottom)? They are pretty damning, and show that his benchmark C++ programs are ridiculously inefficient, leak like a sieve, and improperly measured in any case. The rebuttal benchmarks don't look like they were bunched together by an amateur unfamiliar with the language either.

In the end, the Java Runtime is doing a bunch of stuff that simply doesn't get done in C++. No manner of optimisations are going to make something look like nothing.
