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

You should not be able to notice the difference even if there is any. Besides, in practice, you'll have to do an additional a + 1 or a - 1 to make the condition stand unless you're going to use some magic constants, which is a very bad practice by all means.
