What this data represents: The probe is positioned in the LXC Caddy container in reverse, so it captures all the upload traffic from each container. Therefore, what we see here is the total upload bandwidth of all the containers combined.
My ISP, Orange/Sosh, offers me 800Mbit of upload. I have limited the upload on my LXC container 'caddy' using 'incus config device override caddy eth0 limits.egress=790Mbit' to avoid saturating the network and to be able to continue managing my system container manager, Incus.
