Action Cable is a fantastic interface — if only it would be performant enough in production! Unfortunately, running vanilla Action Cable will result in high memory consumption and poor handling of concurrent requests.

Wouldn’t it be cool to have the interface and bits and gears to handle all the traffic — maybe by rewriting crucial parts to something like Go or Erlang?

Turns out, it’s possible, and it is exactly what AnyCable is — a plug and play solution to boost AC performance.
