Try setting force:false
on your compass config options, there was a previous issue that caused sprites to be regenerated.
Compilation with Compass and sprites is slow regardless. I had a similar problem: Grunt with Compass and Watch compiles slow
Question
This is resulting in an insane compile time: ~20 seconds. Notice that it creates the global-s9e3ed7fd2e.png image 5 times, as opposed to just once for mobile & once for desktop.
I only see @import "sprites/global/*.png";
being called twice, hence my confusion.
Here's the config file: jsfiddle
