https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=268490 --- Comment #14 from Daniel Duerr <duerrd561@gmail.com> --- (In reply to Franco Fichtner from comment #13) Thank you, Franco. I tested what you suggested here but I do not see a change. Here's my `ifconfig` output before (the PROMISC flag is missing as you suggest): igb0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 9000 options=800028<VLAN_MTU,JUMBO_MTU> ether 00:25:90:d6:e6:72 media: Ethernet 1000baseT <full-duplex> status: active nd6 options=29<PERFORMNUD,IFDISABLED,AUTO_LINKLOCAL> igb1: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 9000 options=800028<VLAN_MTU,JUMBO_MTU> ether 00:25:90:d6:e6:72 hwaddr 00:25:90:d6:e6:73 media: Ethernet 1000baseT <full-duplex> status: active nd6 options=29<PERFORMNUD,IFDISABLED,AUTO_LINKLOCAL> And here are the baseline `iperf -s` test numbers to match: [ ID] Interval Transfer Bandwidth [ 1] 0.00-79.38 sec 60.0 Bytes 6.05 bits/sec [ 2] 0.00-76.85 sec 60.0 Bytes 6.25 bits/sec [ 3] 0.00-56.37 sec 60.0 Bytes 8.52 bits/sec [SUM] 0.00-98.92 sec 180 Bytes 14.6 bits/sec I then made the change you suggested: [root@nfs dd]# ifconfig igb0 promisc [root@nfs dd]# ifconfig igb1 promisc Which is reflected in the `ifconfig` output: igb0: flags=28943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST,PPROMISC> metric 0 mtu 9000 options=800028<VLAN_MTU,JUMBO_MTU> ether 00:25:90:d6:e6:72 media: Ethernet 1000baseT <full-duplex> status: active nd6 options=29<PERFORMNUD,IFDISABLED,AUTO_LINKLOCAL> igb1: flags=28943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST,PPROMISC> metric 0 mtu 9000 options=800028<VLAN_MTU,JUMBO_MTU> ether 00:25:90:d6:e6:72 hwaddr 00:25:90:d6:e6:73 media: Ethernet 1000baseT <full-duplex> status: active nd6 options=29<PERFORMNUD,IFDISABLED,AUTO_LINKLOCAL> But the `iperf -s` numbers are still terrible: [ ID] Interval Transfer Bandwidth [ 1] 0.00-68.47 sec 60.0 Bytes 7.01 bits/sec [ 2] 0.00-48.60 sec 60.0 Bytes 9.88 bits/sec [ 3] 0.00-28.25 sec 60.0 Bytes 17.0 bits/sec [SUM] 0.00-70.48 sec 180 Bytes 20.4 bits/sec Do I need to adjust the `lagg` interface to replicate your test, given I'm running inside of a `lagg` interface? -- You are receiving this mail because: You are the assignee for the bug.
