The network configuration of the pve host is shown below: root@pve:~# cat /etc/network/interfaces # network interface settings; autogenerated # Please do NOT modify this file directly, unless you know what # you're doing. # # If you want to manage parts of the network configuration manually, # please utilize the 'source' or 'source-directory' directives to do # so. # PVE will preserve these directives, but will NOT read its network # configuration from sourced files, so do not attempt to move any of # the PVE managed interfaces into external files! auto lo iface lo inet loopback auto enp1s0 iface enp1s0 inet manual ovs_type OVSPort ovs_bridge vmbr0 auto enp2s0 iface enp2s0 inet manual ovs_type OVSPort ovs_bridge vmbr1 iface enp3s0 inet manual iface enp4s0 inet manual iface enp5s0 inet manual iface enp6s0 inet manual auto vmbr0 iface vmbr0 inet static address 192.168.10.254/24 gateway 192.168.10.1 ovs_type OVSBridge ovs_ports enp1s0 auto vmbr1 iface vmbr1 inet manual ovs_type OVSBridge ovs_ports enp2s0 Now I use scp to transfer file from pve (192.168.10.254) to another physical machine (192.168.10.100) or vice versa, but run the following two commands in order: root@pve:~# scp macOS-10.13.qcow2 werner@192.168.10.100:/dev/null werner@192.168.10.100's password: macOS-10.13.qcow2 37% 6209MB 83.6MB/s 02:01 ETA werner@X10DAi:~$ scp macOS-10.13.qcow2 root@192.168.10.254:/dev/null root@192.168.10.254's password: macOS-10.13.qcow2 30% 1408MB 53.5MB/s 01:00 ETA As you can see, the show different network transfer speed. OTOH, if I run the above two commands simultaneously, the results will look like the following: werner@X10DAi:~$ scp macOS-10.13.qcow2 root@192.168.10.254:/dev/null root@192.168.10.254's password: macOS-10.13.qcow2 17% 811MB 26.0MB/s 02:26 ETA root@pve:~# scp macOS-10.13.qcow2 werner@192.168.10.100:/dev/null werner@192.168.10.100's password: macOS-10.13.qcow2 13% 2205MB 51.7MB/s 04:34 ETA Any hints for the above observations and results will be highly appreciated.
