No. It is not the lack of peer-to-peer connections that gives rise to the bottleneck, but the idea of several threads multiplexing sendfile() through a single socket. Given a bad program design, it can be done over TCP too. The conclusion is that the programmer really ought to choose a different design. For multimedia streaming, for instance, it makes sense to use 1 UDP socket per thread rather than to multiplex the output through one socket.
