This is sort of true. I don't know of a way to simply limit the number of incoming sockets without getting a lot of ISP level involvement or just outright rejecting connections. It does limit the number of long-lived sockets for file transfer. On static file serves, I am assuming the cpu has plenty of spare capacity for doing the algorithm, so I am not worried about that. Finally I am assuming the limiting factor is bandwidth here, so bandwidth smoothing the main goal.
