Arduino is Slow - and how to fix it!

Step 4 Overview

Now you know that digitalWrite() takes significantly more time to execute than true c style commands. If you want to use arduino and time is important, I would highly recommend you use these true C style commands in lieu of digitalWrite(). While digitalWrite() is more convenient to change pins with, it takes 10 times longer!

I have attached a little cheat sheet below, print it out so it is handy whenever you need it.

 

I hope you have gotten something useful from this.
