https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D270188 --- Comment #3 from Vladimir Druzenko <vvd@FreeBSD.org> --- About Troubleshooting on Wiki page. Suggest to add just resolved problem on my new installation: very low netwo= rk bandwidth (~2.5Mbit/s on VM via iperf) with bridged network on igb (Intel I= 350 onboard IBM X3550 M4) or lagg with several igb nics. Solution: disable RXCSUM (bw increased in ~300 times) and TXCSUM (+10% more= for bw). In command line: > ifconfig igb0 -rxcsum -txcsum In rc.conf: > ifconfig_igb0=3D"inet IP netmask MASK -rxcsum -txcsum" If use lagg in rc.conf: > ifconfig_igb0=3D"up -rxcsum -txcsum" > ifconfig_igb1=3D"up -rxcsum -txcsum" P.S. Just a note not to lose the solution. And maybe it will help someone e= lse. --=20 You are receiving this mail because: You are on the CC list for the bug.=
