hi! i have an intel etherexpress gigabit card on 100mbit port and fbsd 6.0-p1.. my box is a proxy, it's traffic is 100/100mbit constant.. unfortunately i have to use tunnel and that is the source of my problem. when i enable the tunnel and the packages are going through it the performance is poor.. it seems that it's not full duplex, the speed is around 50/50mbit, and have 10-15% packet loss.. i tried to enable/disable polling, and used these sysctl vars: kern.polling.enable=1 kern.ipc.somaxconn=2048 net.inet.tcp.inflight.enable=0 net.inet.ip.portrange.randomized=0 net.inet.tcp.sendspace=65536 kern.ipc.maxsockbuf=786432 net.inet.tcp.delayed_ack=0 net.inet.tcp.newreno=0 net.inet.ip.intr_queue_maxlen=1024 net.inet.tcp.blackhole=2 net.inet.udp.blackhole=1 net.inet.ip.rtmaxcache=1024 without tunnel the speed is 100/100mbit, great. ps: with linux its all OK, but i wanna use fbsd :)
