Running iperf shows about 20-30Mbits which was almost full GigE = (~900Mbits) speed before. I'm noticing interface errors : [16:37]ndenev@nas:~% netstat -I sge0 Name Mtu Network Address Ipkts Ierrs Idrop = Opkts Oerrs Coll sge0 1500 00:0a:e4:86:62:fa 76114295 42197 0 = 103559806 10324 0 sge0 1500 10.0.0.0 nas 76109575 - - = 119109557 - - Both the switch and the card show 1000 full-duplex. I've tried playing with rxcsum,txcsum,vlanhwtag,tso but disabling even = all of them do not change anything. I've tried different switch port and changed the cable. Here is devinfo for my hardware : sge0 pnpinfo vendor=3D0x1039 device=3D0x0191 subvendor=3D0x103c = subdevice=3D0x2a70 class=3D0x020000 atphy0 pnpinfo oui=3D0xc82e model=3D0x1 rev=3D0x6 at phyno=3D0 Of course all of this can mean hardware problem, I just want to ask if = somebody is seeing something similar, since there are quite a lot minibus related changes as far as I can see. I'll boot RELENG_8 again tomorrow and do a quick test again to verify = that this is not a hardware issue. Regards, Nikolay
