Github user revans2 commented on the pull request: https://github.com/apache/storm/pull/1250#issuecomment-200853358 @roshannaik Yes we need to do a renewed effort in profiling once a lot of the code has moved to java for JStorm. I know that the throughput is about 1/2 of what it is in 0.10, and 1.0. I didn't do any profiling, but I have chocked it up to clojure reflection showing up again, because anytime clojure calls into java it is ridiculously easy to have clojure use reflection to get the job done. But I have not profiled so I don't know for sure.
