Benchmarks are merciless

• JavaScript vs. Python
• PHP vs. Python

A number 1/4 for A vs. B means that B is 4 times slower than A.

The Computer Language Benchmarks Game is more a community benchmark than a programming language benchmark. You get some ballpark figures that confirm what you already know beforehand: C++ is faster than Ruby :-)

But it's still depressing to see that a current implementation of JavaScript is faster than Python.
