Performance comparison of Functional C++ 11, Java 8, JavaScript and Wolfram

Only computation-heavy code will show a difference. And the disparity is going to vary a lot. Some code will be easy for Java's optimizer and won't give C++ any advantage.

Some will even put C++ at a disadvantage.

Out of curiosity any such examples ?

Of course there are, and it only takes a few seconds with Google to find them. Here's one: the frannkuch-redux benchmark at http://benchmarksgame.alioth.debian.org/u64q/java.php gives Java a >20% CPU efficiency advantage over C++.

That compares a Java program written to use multiple cores with a C++ program not written to use multiple cores; because the C++ programs written to use multiple cores did not compile.

See http://benchmarksgame.alioth.debian.org/u64q/performance.php...
