Hello, I've recently upgraded a box running RELENG_8 to RELENG_9 and immediately I noticed much slower network connection. 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 <Link#4> 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=0x1039 device=0x0191 subvendor=0x103c subdevice=0x2a70 class=0x020000 atphy0 pnpinfo oui=0xc82e model=0x1 rev=0x6 at phyno=0 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
