Playing with ActionCable

This repository is an incredibly simple Rails server that includes an ActionCable channel. I wanted to experiment with ActionCable specifically to see how it performs under load.

To run the tests:

• Start the server rails s -b 0.0.0.0 (don't use localhost)
• Open a browser to https://localhost:3000, this will open a single connection and channel subscription
• Create 2,500 connections each with a single channel subscription node test-actioncable.js

Ably realtime messaging

A test script exists to connect to Ably and publish a high volume of messages quickly, see test-ably.js. However, please note that your tests may not provide useful results for the following reason:

• The websocket servers are not local so there is increased latency
• You need an account and API key to connect to Ably, sign up for a free account first
• You need to obtain your API key from your dashboard and add it to the test-ably.js script.
