node is evented and non-blocking it is very good at handling concurrent requests, so a proxy built on Node will perform much better than one built on say Ruby.

Ruby is a programming language and Node.js is a system written in Javascript. It is useless to compare Node.js to Ruby. There is a similar system to Node.js in Ruby, it's called Event Machine. The official Node.js about page states "Node is similar in design to and influenced by systems like Ruby's Event Machine or Python's Twisted."
