And if swapping the ordering of the tests doesn't convince you, then try constructing both arrays using the same method.

You'll find that the benchmark shows a difference even when they are both constructed the same way.

It's worth bearing in mind that given the huge numbers of iterations being performed, even the largest (12%) difference shown, represents a difference of 0.000,000,014 of a second which hardly makes it a "large difference".
