I install the pve on an I7 8886U machine with 6 full-duplex gigabit
network cards. The network configuration of the pve host is shown
below:
<quote>
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!

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 [email protected]:/dev/null
[email protected]'s password:
macOS-10.13.qcow2 37% 6209MB 83.6MB/s 02:01 ETA
werner@X10DAi:~$ scp macOS-10.13.qcow2 [email protected]:/dev/null
[email protected]'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 [email protected]:/dev/null
[email protected]'s password:
macOS-10.13.qcow2 17% 811MB
26.0MB/s 02:26 ETA
root@pve:~# scp macOS-10.13.qcow2 [email protected]:/dev/null
[email protected]'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.
