Honestly, when I use SASS/Coffeescript it's not performance I'm thinking about. Most of the time it doesn't matter for the stuff I make. The reason I use these things is simply so I can type less. I don't have to type brackets/semicolons, I get all the syntax shortcuts in Coffeescript, whatever. It's so restricting when you can't type as fast as you think, and JS -> Coffeescript gets you closer.
