Scaling Realtime at DISQUS
Disqus' realtime architecture -- nginx PushStream module doing the heavy lifting, basically. See https://gist.github.com/dctrwatson/0b3b52050254e273ff11 for the production nginx configs they use. I am very impressed that push-stream has grown to be so solid; it's a great way to deal with push from the sounds of it.

http://blog.disqus.com/post/51155103801/trying-out-this-go-thing now notes that some of the realtime backends are in Go.

https://speakerdeck.com/dctrwatson/c1m-and-nginx ("C1M and Nginx") is a more up to date presentation. It notes that PushStream supports "EventSource, WebSocket, Long Polling, and forever iframe". More sysctls and nginx tuning in that prez.
