@draco, maybe it is a good idea to redo the benchmark with the new fix, because it seems really that Chris put its finger on the beast ! ;)

#15641 The reason latency is improved with this change is actually quite simple. The call to delay(5000) is used to wait for the packet delivery confirmation, but no more than 5 seconds. So the latency is not really associated with the delay() call, it is due to the fact that TCP ACK does not come immediately.
Perhaps calling tcp_output() improves latency somewhat, but you really need to wait for ACK afterwards, otherwise just use UDP.
