I isolated the problem: it was not really using 192.168.1.149, but instead 192.168.1.145 (the builtin bge0). This is despite the -N and what the output reported. FYI: bge0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500 options=8009b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM,LINKSTATE> ### inet 192.168.1.145 netmask 0xffffff00 broadcast 192.168.1.255 media: Ethernet autoselect (1000baseT <full-duplex>) status: active nd6 options=23<PERFORMNUD,ACCEPT_RTADV,AUTO_LINKLOCAL> ue0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500 options=68009b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM,LINKSTATE,RXCSUM_IPV6,TXCSUM_IPV6> ### inet 192.168.1.149 netmask 0xffffff00 broadcast 192.168.1.255 media: Ethernet autoselect (1000baseT <full-duplex>) status: active nd6 options=29<PERFORMNUD,IFDISABLED,AUTO_LINKLOCAL> After using: # ifconfig bge0 down things behaved with speeds that USB2 can handle: # iperf3 -c 192.168.1.120 -B 192.168.1.149 --get-server-output Connecting to host 192.168.1.120, port 5201 [ 5] local 192.168.1.149 port 62507 connected to 192.168.1.120 port 5201 [ ID] Interval Transfer Bitrate Retr Cwnd [ 5] 0.00-1.00 sec 15.9 MBytes 133 Mbits/sec 2 115 KBytes [ 5] 1.00-2.00 sec 15.6 MBytes 131 Mbits/sec 4 111 KBytes [ 5] 2.00-3.00 sec 15.7 MBytes 131 Mbits/sec 4 101 KBytes [ 5] 3.00-4.00 sec 15.6 MBytes 131 Mbits/sec 5 84.1 KBytes [ 5] 4.00-5.00 sec 15.6 MBytes 131 Mbits/sec 3 62.7 KBytes [ 5] 5.00-6.00 sec 15.7 MBytes 131 Mbits/sec 5 39.9 KBytes [ 5] 6.00-7.00 sec 15.7 MBytes 131 Mbits/sec 5 34.2 KBytes [ 5] 7.00-8.00 sec 15.7 MBytes 131 Mbits/sec 3 9.98 KBytes [ 5] 8.00-9.00 sec 15.6 MBytes 131 Mbits/sec 4 15.7 KBytes [ 5] 9.00-10.00 sec 15.6 MBytes 131 Mbits/sec 4 123 KBytes - - - - - - - - - - - - - - - - - - - - - - - - - [ ID] Interval Transfer Bitrate Retr [ 5] 0.00-10.00 sec 157 MBytes 131 Mbits/sec 39 sender [ 5] 0.00-10.98 sec 157 MBytes 120 Mbits/sec receiver Server output: ----------------------------------------------------------- Server listening on 5201 ----------------------------------------------------------- Accepted connection from 192.168.1.149, port 42844 [ 5] local 192.168.1.120 port 5201 connected to 192.168.1.149 port 62507 [ ID] Interval Transfer Bitrate [ 5] 0.00-1.00 sec 424 KBytes 3.48 Mbits/sec [ 5] 1.00-2.00 sec 15.7 MBytes 131 Mbits/sec [ 5] 2.00-3.00 sec 15.6 MBytes 131 Mbits/sec [ 5] 3.00-4.00 sec 15.6 MBytes 131 Mbits/sec [ 5] 4.00-5.00 sec 15.6 MBytes 131 Mbits/sec [ 5] 5.00-6.00 sec 15.6 MBytes 131 Mbits/sec [ 5] 6.00-7.00 sec 15.6 MBytes 131 Mbits/sec [ 5] 7.00-8.00 sec 15.6 MBytes 131 Mbits/sec [ 5] 8.00-9.00 sec 15.7 MBytes 131 Mbits/sec [ 5] 9.00-10.00 sec 15.6 MBytes 131 Mbits/sec [ 5] 10.00-10.98 sec 15.3 MBytes 131 Mbits/sec - - - - - - - - - - - - - - - - - - - - - - - - - [ ID] Interval Transfer Bitrate And: # iperf3 -R -c 192.168.1.120 -B 192.168.1.149 --get-server-output Connecting to host 192.168.1.120, port 5201 Reverse mode, remote host 192.168.1.120 is sending [ 5] local 192.168.1.149 port 61744 connected to 192.168.1.120 port 5201 [ ID] Interval Transfer Bitrate [ 5] 0.00-1.00 sec 13.7 MBytes 115 Mbits/sec [ 5] 1.00-2.00 sec 13.5 MBytes 114 Mbits/sec [ 5] 2.00-3.00 sec 13.5 MBytes 114 Mbits/sec [ 5] 3.00-4.00 sec 13.5 MBytes 113 Mbits/sec [ 5] 4.00-5.00 sec 13.6 MBytes 114 Mbits/sec [ 5] 5.00-6.00 sec 13.5 MBytes 113 Mbits/sec [ 5] 6.00-7.00 sec 13.5 MBytes 113 Mbits/sec [ 5] 7.00-8.00 sec 13.5 MBytes 113 Mbits/sec [ 5] 8.00-9.00 sec 13.5 MBytes 113 Mbits/sec [ 5] 9.00-10.00 sec 13.4 MBytes 113 Mbits/sec - - - - - - - - - - - - - - - - - - - - - - - - - [ ID] Interval Transfer Bitrate Retr [ 5] 0.00-10.84 sec 135 MBytes 105 Mbits/sec 12652 sender [ 5] 0.00-10.00 sec 135 MBytes 113 Mbits/sec receiver Server output: ----------------------------------------------------------- Server listening on 5201 ----------------------------------------------------------- Accepted connection from 192.168.1.149, port 12490 [ 5] local 192.168.1.120 port 5201 connected to 192.168.1.149 port 61744 [ ID] Interval Transfer Bitrate Retr Cwnd [ 5] 0.00-1.00 sec 2.25 MBytes 18.9 Mbits/sec 186 30.1 KBytes [ 5] 1.00-2.00 sec 13.7 MBytes 115 Mbits/sec 1242 34.4 KBytes [ 5] 2.00-3.00 sec 13.5 MBytes 113 Mbits/sec 1291 27.3 KBytes [ 5] 3.00-4.00 sec 13.5 MBytes 114 Mbits/sec 1242 34.5 KBytes [ 5] 4.00-5.00 sec 13.5 MBytes 113 Mbits/sec 1302 25.8 KBytes [ 5] 5.00-6.00 sec 13.6 MBytes 114 Mbits/sec 1249 27.3 KBytes [ 5] 6.00-7.00 sec 13.4 MBytes 113 Mbits/sec 1285 21.6 KBytes [ 5] 7.00-8.00 sec 13.5 MBytes 113 Mbits/sec 1238 33.0 KBytes [ 5] 8.00-9.00 sec 13.6 MBytes 114 Mbits/sec 1260 31.6 KBytes [ 5] 9.00-10.00 sec 13.5 MBytes 113 Mbits/sec 1256 25.9 KBytes [ 5] 10.00-10.84 sec 11.3 MBytes 112 Mbits/sec 1101 18.8 KBytes - - - - - - - - - - - - - - - - - - - - - - - - - [ ID] Interval Transfer Bitrate Retr [ 5] 0.00-10.84 sec 135 MBytes 105 Mbits/sec 12652 sender iperf Done.
