We benchmarked round-trip times with Secure WebSockets (wss://) vs HTTPS to see if there was a noticeable difference in response speed. For Secure WebSockets, we timed the difference between the client sending a “ping” packet, and the server responding with “pong”. This included going through an Akka router that managed the Play! Iteratees. For standard HTTPS, we timed the round-trip of the client initiating a request to an endpoint that immediately replies with “Ok”. The sample size is 1000 per type.
