Not a game programmer, but do a lot of multithreaded work. There's about 100000 ways to pass messages in c++, for some c++ is faster (purely bounded by cache communication), some erlang is faster, and for some it's hard to compare (send latency, receive latency, throughput, can all vary greatly). That only applies for two processes running on a single machine, Erlang can automatically distribute workers (I believe) and in that case it's probably more about networking hardware than language.
