I Miss Rails - Hackdot

I'm interested in hearing about applications successfully using ActionCable for what and how. It's unclear to me how much use it's getting, or how well it meets actual use cases.

ActionCable is super easy to use out of the box to get WebSockets running, but it's incredibly non-performant. Anything more than 100 concurrent users took the time taken to a send a message to the socket from milliseconds to seconds. Replacing it with the AnyCable gem in conjunction with AnyCable-Go got us to over 1000 concurrent users without a hitch.

Is Redis the bottleneck?

Nope it was Ruby / Rails itself.

Was it an issue with Passenger and the number of concurrent connections it could hold?

I just deployed ActionCable into production yesterday. I’ll be using it to share some information between our users’ mobile app and our web client.

I’m concerned about performance. As much as I know that premature optimization is the Devil, it’s hard to stomach deploying something that is so notorious for becoming a bottleneck. Once I get past my MVP of this feature and have some maintenance hours budgeted, I plan on exploring AnyCable.
