Miles/Andrew polling increased dramaticly the latency for all traffic that passes trough the bridge and reduced the transmission rate also. with polling: rtt min/avg/max/mdev = 1.472/2.005/2.651/0.393 ms without polling: rtt min/avg/max/mdev = 0.642/0.735/1.111/0.134 ms Thanks in advance -- Alexandre Vieira - nullpt@gmail.com
