I didn't have to answer :) Thank you for looking it up. Erlang also enjoys quite a lot of optimizations on the VM level. E.g. a task is parked/hybernated if there's no work for it to perform (e.g. it's waiting for a message), the switch between tasks is extremely lightweight, VM internals are re-entrant, employ CPU-cache-friendly data structures, garbage collection is both lightweight and per-thread/task etc.
