>"But if you're just serving HTTP requests, just avoid it entirely if you can because any performance gain is probably imaginary but the complexity increase isn't" I serve HTTP requests offering JSON based RPC in my C++ servers that do all kinds of calculations (often CPU consuming) in multiple threads. Works just fine and scales well. Yes I have to be careful on how I work with shared data but it is centralized encapsulated and done in a single place I call request router / controller. I reuse it among the projects. Nothing too exciting about it and no reason to be scare do death ;)
