So what is the performance benchmark for Clojure / ClojureScript? I've seen a lot of buzz for Clojure as of late, but given how bloated the web is at the moment, until I see Clojure (or Haskell) make leaps-and-bounds better performance in return for the pain of learning the language (and the barrier to functional programming), how can we hope to mass-adopt this technology?

Performance isn't everything and in many cases not that important. Clojure and Haskell make leaps-and-bounds better performance than Python and Ruby which both have mass adoption.
