Is it realistic to use ActionController::Live for a site with a lot of visitors?

Question

Ruby on Rails

I read the Habr article Streaming in Rails 4 .
Let's say we have a website. 5000 people can sit online (just open a tab). For example, a social network. What new user should receive instantly.
Suppose the server is rather weak (vds with 1GB of memory).
How realistic is it to use ActionController::Live for such a task, or is it necessary to use EM / node.js and nothing else?

Answer 1

You can use faye (a wrapper for EM with server and client side, something like socket.io for ruby). For it, you can google usage examples in rail (and you can also see an example code with authorization for it here https://github.com/ryanb/private_pub)
