"The main difference is that eventlet can’t influence the Python runtime, but actors are built into Erlang at a language level, so the Erlang VM can do some cool stuff like mapping actors to kernel threads (one per core) and preemption. We get around this problem by launching one API server per core and load balancing with nginx."

The actor model is for concurrency, which is when your threads are communicating with one another, right? What about the task that the API server does requires inter-thread communication?
