I don’t know what you mean by web-scale, you’d be mistaken if you meant “the multi-threaded services that power giant internet properties”. If you want extreme low contention extreme high-utilization, you’re doing threading and event-driven simultaneously, there are no easy answers on heavily contended data structures because you can’t duplicate to exploit immutability if mere insane complexity is an alternative, and mistakes cost millions in real time. There’s a reason why those places scout so heavily for the lock-free/wait-free galaxy brains the minute they finish their PhDs.
