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:
without tunnel the speed is 100/100mbit, great.
ps: with linux its all OK, but i wanna use fbsd :)
