>But how well does this scale to 100K users? It wouldn't. Designing a system to handle 100k simultaneous users is hard, and a problem few people suffer from.

  Why would you ask this question? Because maybe he is looking to develop a chat system that can scale to 100,000 users? There are many instances where someone is tasked to look at a technology and understand how it scales. Frankly, it would be helpful for you to tell us how "It wouldn't"

    Because the order of magnitude is insane. It's a) not a common problem, and b) is obviously non trivial with current technology. The bandwidth necessary for 100k users would saturate many a pipe, and would immediately require more than one commoditized machine. It's like saying "That's a cute little Prius you got there. How many semi trailers can it pull?"

  In my experience, a single node web socket server has trouble with 5,000 concurrent connections nonetheless 100,000 connections.

    No reason why it can't scale. Spawn up more processes, load balance.
