It would be interesting to see results of this benchmark from other platforms; these are operations where the efficiency definitely depends on the underlying hardware.
Since >= and < took almost exactly the same amount
of time, I conjectured that $foo >= $bar might get translated to $bar < $foo by the compiler, but this appears to not be the case:
But then, $foo >= $bar is actually equivalent to $bar <= $foo, so you don't gain anything by doing the conversion. :)
