I did say its significant on upstream
The table clearly shows we behind the times in live media entertainment tho.
VM really simply need to enforce a quite strict upload usage that applies 24/7 (given congestion isnt just peak) and that severely restricts upload speed when this limit is reached, it should apply to 'all' traffic. Basically if you like a much stricter STM thats 24/7. As well as forcefully keep upstream ports to below 40% utilisation, to allow the optimistic 10mbit upload for 1 user per channel.
