Real World App/API Response Time Bemchmark?

Something that I _really_ want to address from an Engineering/Perf perspective is the round-trip response time for a typical API request.

Rust #103 is unquestionably faster than Elixir https://github.com/dwyl/learn-elixir/issues/102 in synthetic benchmarks. But what if we consider the full request lifecycle? What about our *specific* use case which is long-lived websocket connections for collaboration across many teams? Which stack will end up with the best performance / lowest latency?
