I know that by tuning these TCP parameters : tcp_deferred_ack_interval=1 tcp_mss_min=536 tcp_rwin_mss_multiplier=36 tcp_dupack_fast_retransmit=4 tcp_mss_def=536 tcp_rexmit_interval_max=2000 tcp_rexmit_interval_min=2000 tcp_rexmit_interval_initial=2000 that improve the speed and lower the latency, hence a better ping? I know the ''ndd'' app can be used to tune them manually, but programatically, how? How, on Open Transport? I read a lot of docs already, and found nothing
