If I was you I would give Rollup a try: http://rollupjs.org

I used to minify with Closure as well (through r.js) and it would take forever.

We're using Browserify — can you use Rollup with it? Closure's slowness isn't really a problem for us since we only use it for deploys, not while deveoping.

Edit: I see, Rollup is a competitor to Browserify. Looks nice, if somewhat immature. Maybe we'll be able to use it.
