I wish I knew what to tell you. I've never seen more than a minute on our codebase for Uglify. It could also be we were doing something stupid with Closure and slowing it down (like stopping then spinning up the JVM for each package for example) which is certainly possible. However if we add in some of the more computationally heavy Uglify options it will go up somewhat.
