July 27, 20233 yr Under kernel 4.9, using a usb3.0 to Gigabit interface with RTL8153b card, the upstream and downstream speed can reach Gigabit. But with kernel5.10, the speed can't reach gigabit, and the driver file has been changed to the latest version, but still no effect. kernel5.10 Speed measurement root@orangepi3-lts:~# iperf3 -c 192.168.3.201 Connecting to host 192.168.3.201, port 5201 [ 5] local 192.168.3.146 port 44376 connected to 192.168.3.201 port 5201 [ ID] Interval Transfer Bitrate Retr Cwnd [ 5] 0.00-1.00 sec 24.8 MBytes 208 Mbits/sec 0 147 KBytes [ 5] 1.00-2.00 sec 23.5 MBytes 198 Mbits/sec 0 147 KBytes [ 5] 2.00-3.00 sec 23.5 MBytes 197 Mbits/sec 0 147 KBytes [ 5] 3.00-3.15 sec 3.66 MBytes 202 Mbits/sec 0 147 KBytes root@orangepi3-lts:~# iperf3 -c 192.168.3.201 -R Connecting to host 192.168.3.201, port 5201 Reverse mode, remote host 192.168.3.201 is sending [ 5] local 192.168.3.146 port 44380 connected to 192.168.3.201 port 5201 [ ID] Interval Transfer Bitrate [ 5] 0.00-1.00 sec 47.5 MBytes 399 Mbits/sec [ 5] 1.00-2.00 sec 48.4 MBytes 406 Mbits/sec [ 5] 2.00-2.99 sec 48.1 MBytes 406 Mbits/sec root@orangepi3-lts:~# lsusb -t /: Bus 06.Port 1: Dev 1, Class=root_hub, Driver=ohci-platform/1p, 12M /: Bus 05.Port 1: Dev 1, Class=root_hub, Driver=ohci-platform/1p, 12M /: Bus 04.Port 1: Dev 1, Class=root_hub, Driver=ehci-platform/1p, 480M /: Bus 03.Port 1: Dev 1, Class=root_hub, Driver=ehci-platform/1p, 480M /: Bus 02.Port 1: Dev 1, Class=root_hub, Driver=xhci-hcd/1p, 5000M |__ Port 1: Dev 2, If 0, Class=Vendor Specific Class, Driver=r8152, 5000M /: Bus 01.Port 1: Dev 1, Class=root_hub, Driver=xhci-hcd/1p, 480M Edited July 27, 20233 yr by sakesm
