I never used Erlang, and I'm a functional programming fan. But languages based on heavy VM that abstract OS away always make me doubt that's the right direction.

What makes you think the BEAM VM is "heavy"?

It's almost like an OS in itself and initially designed to be like a more capable and robust OS on top of rather constrained computers. In my experience it's trivial to shell or port out to the environment when I want to, and I also see people that I don't think of as highly skilled low-level programmers do things with NIF:s so that can't be exceptionally demanding either.

Yes it's definitely not heavy like a Java program that will cannibalize your RAM.

It's actually quite lean.

It will use all your cores without you asking (which is fantastic right?) but it's configurable AFAIK.
