I know Erlang, not impressed by its performance, I get better performance using C alone (the same language the Erlang run-time is implemented in), but the same can be said for C# 4.0, even, so it's not hard. It hurts, I know, but it's a fact. Computers are imperative, one instruction at the time and nothing can eclipse that fact. Then I guess it hurt more when you got told that Ericsson kicked Erlang to the trash can a long time ago.
