Your claim does not line up with reality. http://shootout.alioth.debian.org/u32/which-programming-languages-are-fastest.php http://shootout.alioth.debian.org/u3

  I think it is interesting you point the parent out for not lining up with reality. Can you elaborate on how the benchmarks in the above posts are a more realistic way to reason about the performance than the experience of the language used in a real life project?

    These exact same techniques used in these benchmarks are used in "real life" projects, for example this one that I work on: https://github.com/clojure/core.logic https://github.com/clojure/core.logic This is a Prolog-like engine that I benchmark against SWI-Prolog (written in C). It comes close on some benchmarks, and surprisingly surpasses on a few.

      Fair enough, however I don't see a benchmark which measures the performance of Clojure in a situation described as above (dealing with a lot of mutable java objects) compared to other (JVM) languages. He clearly mentioned, for such tasks, clojure is 1000 times slower than Kawa. The fact that Clojure is fast for other types of programming problems is irrelevant for this particular case.

        If the poster had could give a (minimal) example to demonstrate their claims, then we could know for sure. Otherwise, we have no idea what the problem was.
