too low traffic in ntopng

Hi!
Just out of curiosity I wanted to know, what happens in my network at home, for example which Netflix-Traffic is going through the network.
I have installed ntopng on the box, but the traffic is not matching up. If I am watching 4k on Netflix I would expecting 15 Mbit/s but I get 3 Mbit/s or something like that.
Are there any mo

Hi!
Is this something someone could acknowledge or deny?

The first thing that comes to mind is the that netflix uses a playback buffer. So if it builds up enough packets it won't need to use as much bandwidth to have enough frames to playback on the tv.

Yeah expecting netflix to be Xmbps is not really a good test... What does your traffic graph show in real time, and then what does ntop report?

Agree, I was forced to use Netflix via LTE in Germany at one point as the WiFi on site was so bad and accidentally startet a 4k stream. Wasn't so bad at all, as compression, codecs, audio etc. all have to come together to get you to ~15Mbps. If it's a fairly good codec and the pictures are good to compress I'd guess with stereo or a reduced audio band you can get it done with around 3-5Mbps. Add in caching etc. and you won't get near the expected numbers :)
