I want to state that performance is too generalize here.

BEAM VM also have a goal of low latency which can be consider as performance. I'm not entirely sure if GO is aiming for that or not. I would never do any numerical stuff on BEAM though, it's very slow.

This article is a bit dated but is interesting between Go and Erlang:
