Why is Erlang said to be more suited for server side programming in webgames than Java and C++?

Question

I don\'t really understand, how can Erlang be more efficient than C++?

Answer 1

Erlang is far less efficient than C++. Erlang's big strength is scalability, not efficiency. It will linearly scale across multiple CPUs and, due to its programming and communications model, will very easily scale across machine clusters.

Just to be clear, Erlang won't scale more than C++; it just scales more easily than C++. A lot more easily. See chapters 5 and 6 of Concurrent Programming in Erlang for a very good explanation of why this is so.
