>>> One of Clojure's biggest weaknesses in practice is that breaking in to those functional structures to figure out where the time is being spent or to debug them is harder than in other languages. This is a natural trade-off of developing a terse and powerful language. Not that hard if you use something like YourKit. There's also a quite good Clojure library https://github.com/hugoduncan/criterium https://github.com/hugoduncan/criterium .
