I'm writing an elixir app that runs raw WebSockets over cowboy, and I'm at a point where things work and I'd like to make them fast. But to do that, I feel that I need get automated benchmarks working. I know of a lot of tools that can benchmark over HTTP, but I've never done this for WebSockets.
From what I've looked, I've found a bunch of npm packages that claim to do WebSocket benchmarking, but nothing seems to stand out. Ideally I'd need something that can use my custom binary protocol during the benchmark.
What tool would you guys recommend?
