[erlang-questions] Erlang doesn't suck

I would like notice that hipe can cause performance lost for some special
cases. There is not simple equation, switch on hipe and you gain some amount
of performance surplus. Especially when you have tight loop over not so much
complex data structures you can gain big amount of performance. When you do
big amount of inter module calls you gain less and when you do big amount of
message passings you can lost some performance when switch it on.
