> Currently, a state.json request travels through the master's mailbox twice: before authorization and after. This increases the overall state.json response time by around 30%.
> To remove one mailbox trip, we can perform the initial portion (validation and authorization) of state and /state off the master actor by using a top-level {{Route}}, then dispatch onto the master actor only for json / protobuf serialization. This should drop the authorization time down to near 0 if it's indeed mostly queuing delay.
