I don't think any advice you can get from highscalability.com can be any good, because their whole mission statement is crap. They talk about getting 10 million concurrent clients only; they don't talk about scaling in any other dimension. And you'll never have 10 million clients of one server in practice, because how much network bandwidth does your super server have? 10 gbps? So that means you'll be strangling each client down to only a few kbps - way to go for performance. The 1980s called, they want their network apps back. In real life, you'd offload the task from the server onto middle-tier machines that talk to the clients. There'll be at most thousands of these, and each one would have at most thousands of clients. And this will let you provide several mbps to each client if you get the networking right. In fact, it means that even highscalability.com's original mission statement of 10 thousand clients was moot in the first place.
