Google made many many TCP tweaks. Increased initial window, small RTO,
enabled ignore after idle and others. They published that, other people
just blindly applied these tunings and the Internet still works.

Did you try to use ipfw instead of RADIX_MPATH?
Try something like this:

ipfw add $number fwd $router ip from $ip2 to any out via $if2

Will it be possible to process both two channels of 1Gb?

Hi,
Yes, that helps. Source IP address is now the same as destination.
Also helps reconfigure main interface, and now source IP address is
127.0.0.1 (and that's correct behaviour).

I see that you use MTU 9000, have you tried to increase kern.ipc.nmbjumbo9?
Can you also show output of `vmstat -z | grep mbuf'?

Hi,
Maybe you're right.
OK, let's return default hw.igb.rxd to 256. It seems to be enough for
stable work and driver is used less memory.
BTW, on the man page igb(4) still written that hw.igb.rxd equals to 256
by default.

My point is if you're using machine with 8 CPUs than
maxusers/clusters/9k mbufs should have been increased by system, because
on this machine minimum 2Gb memory is available.
