My experience is that it does. I tested up to 32 cores/threads last year and saw linear growth to 8-14 cores. Erlang R13B is supposed to break the 8-14 barrier and the brand new R13B01 goes even further to remove non-parallelisms in the Erlang VM. I'd suggest you try and make sure to try Erlang R13B01.
