If() statements definitely slow programs down. BUT, the size of the
code inside the if satement isn't the real issue. It's the process of
making the true/false decision that takes the work. Of course, the
longer the code inside the if statement, the longer it takes run that
particular part of the code if that code is executed.

Regarding includes, they add overhead. Includes come in handy where
the included file is used in other scripts too.

Yep. That's the simplest thing to do, but I believe there are
benchmarking classes/functions out there.
