Have a look at Rich Hickey's keynote presentation from Conj2011; http://blip.tv/clojure/rich-hickey-keynote-5970064
He pretty much starts off by talking about making Clojure "leaner", faster at starting up etc.
He mentions stuff like a "production" jar with less metadata, hoisted evaluator and even some kind of tree shaking ala ProGuard.
