Indeed the Phoenix benchmark with 2M concurrent connections https://phoenixframework.org/blog/the-road-to-2-million-websocket-connections https://phoenixframework.org/blog/the-road-to-2-million-webs... was on a 40core/128gb machine but the load was a pretty realistic "real world" use case. If @lganzzzo's oatpp can indeed handle 2M concurrent on 8core/52GB with _presence_ and real data being communicated/broadcast it would be worth looking into. We use Phoenix for a number of projects and in addition to handling lots of Websocket connections it's a fully featured framework with an excellent workflow, expressive ORM and seamless DevOps. Seems like oatpp has been built with a single purpose in mind (similar to Redis). Always good to see people diving deep into a topic to push the boundaries of the state of the art.
