Basically it creates a Madbelbrot set and provides time it took. Effects may be surprising.
Fact number 1 - PHP is getting faster
PHP7 with JIT was a winner in an original test (we didn't tested it yet), which is very intersting fact and we are thrilled about how Facebook's HHVM team may respond to that.
Fact number 2 - HHVM is faster than any stable PHP
This is a fact that we have mentioned before, but you can see the difference now very clearly.
Fact number 3 - PyPy is awesome
If you write python apps - try using PyPy. Python itself went quite bad in this test, but with PyPy it took just 0.03s to which is twice as fast as NodeJS and very close to gcc.
