Well the link you posted is not very useful - Javascript is faster on a trigonometry benchmark and the author admits it's probably because GCC's trigonometry functions are probably slow and not optimized. If you switch them out to use better functions or use a different compiler, I imagine the time would go down.

This is probably a better comparison: https://benchmarksgame-team.pages.debian.net/benchmarksgame/

Altough it seems to only have been run on node.js for Javascript.
