I can speak some to the Elixir tech it is built on. It should be low, even with load. The Erlang VM is very good with concurrency and keeping latencies consistent and low. The presence feature could be slower since that propagates a bit more complexly than the broadcasts would. Of course the latency can go up with load but it shouldn't get very spiky thanks to the preemptive multitasking.
