Actually this microservices approach has existed for decades in erlang/otp and can maintain quite excellent speed. You're not going to beat raw c speed-wise, but typically you will beat comparable dynamic languages -- and you don't have to worry about decoding/encoding json or any of that bs. I'd personally be absolutely thrilled if something like genserver and some other otp protocols were ported to other dynamic languages -- but alas real processes aren't nearly efficient enough.
