>Edit: even Haskell seems to be about 7x faster than Erlang (according to [1]). Suddenly, Haskell looks like a good candidate for writing a distributed server :) Can somebody comment on this? One of the best kept secrets of Haskell, it can be very fast, supports multiple concurrency/parallelism options. The Yesod team does interesting performance work on the Warp server: http://www.yesodweb.com/blog/2014/02/new-warp http://www.yesodweb.com/blog/2014/02/new-warp That said, Erlang is really fast at things it was designed for. Try downloading Zotonic or some other Erlang app, get it running, and compare to others like Rails. Sharp, responsive, fast.
