How fast a website or browser gets you to where you need to be without you needing to yell at it. If you don't have to click more than three times, it's E-ficient. If you're clicking like a caffeinated monkey, it's not.
I tried to log in and it took me 12 clicks. This site is a waste of my life.
This browser is so slow, I could have walked to my mom’s house by now.
I clicked 10 links just to get to the settings. This site is a nightmare.
