Same here, I found the concepts in Clojure attractive and elegant but the implementation to be lacking. The toolchain is extremely heavyweight and any promised performance, scalability and development improvements just don't materialise. Like you, I've only tried toy projects, but Clojures weight and lack of real (as opposed to promised) improvement never occurred for me. Also, there seems to be constant discussions on the Clojure forums about the lack of performance.... and they all get resolved by admitting that you need to fallback to non-idiomatic Clojure (i.e. just doing it the Java way).
