I would love to see a comparison between Proxygen and another server (ideally nginx or golang server). The numbers are impressive, but the client is on the same box, it is a big box, and it is a simple and short response. So I'm not sure if I should be wowed or not. From reading the post, Proxygen was written as a server that would be well-integrated into Facebook tools. I don't really use Facebook tools, so I'm not sure if Proxygen would be right for me?
It's a library that you can integrate into your application rather than passing requests via an intermediary (so performance would improve). It's not necessarily a better solution unless you're optimizing for performance. It probably isn't if you're going for ease of development and maintainability.
