Is < faster than <=?

Question

Is if( a < 901 ) faster than if( a <= 900 ).

Not exactly as in this simple example, but there are slight performance changes on loop

Answer 1

At the very least, if this were true a compiler could trivially optimise a <= b to !(a > b), and so even if the comparison itself were actually slower, with all but the most naive compiler you would not notice a difference.
