It depends if you run the full node with open port 8333 to allow incoming connections or not.
My full node allows incoming connections and these are my values:
The download volume is quite low, about 0.5 GB - 1 GB per day
The upload volume is high compared to the download volume. It is at about 17 GB per day.
I don't know if this depends on the peers you are connected to or your internet speed, but that 17 GB upload volume per day was quite stable over the last months.
My internet connection is 100 Mbit down and 10 Mbit upload with no volume limit.
Thank you!
Is it possible to somehow limit the speed of the node on Ubuntu-server?
And is there a dependence on uPNP?
No need for UPnP. If you have a router/firewall, you will need to manually open port 8333 if you want to allow incoming connections. You also might need to tell your node the external address to advertise if it can't determine it automatically (I use the 'externalip' statement to specify both the IPv4 and IPv6 addresses for my node).
