I’m at PolyConf in Poland today, and I watched this super interesting talk by Leandro Pereira about Lwan, an ~8000 line of code web server. He talked about a bunch of the optimizations they’d done (improve CPU cache performance! be really careful about locking!). You can read more about the performance on the website & the links there.
