I am a clumsy individual. Dropping the int call resulted in shaving 3.5 seconds. But how is this possible?! It's ridiculous, really!

The CPython interpreter is pretty naive, so it more or less does what you tell it to.

PHP is no better, if you add an intval call it will add almost 4 seconds to the result! This is an extraordinary proof that being a little sloppy can cost you a lot when using interpreted scripting languages!

Also, I am thinking if and how much speed gain could one inject by not using OOP in PHP...
