Really? DOCSIS has been the bottleneck out of Wi-Fi, DOCSIS, and wider Internet every time I've had the misfortune of having to use it in an apartment.
Especially the tiny uplink frequency slice of DOCSIS 3 and below is pathetic.
That's a bottleneck getting data out of the DOCSIS network, into your home network.
There's far more bandwidth within the DOCSIS network than can enter and exit it, which is why running communication tests between DOCSIS devices has no effect on the the usefulness of the network.
Fun fact: The current workaround to the slowness of DOCSIS modems is to put more modems in your modem and trunk then together, so you can get gigabit speeds with 100+ megabit upstream, by simply having a half dozen or more concurrent connections.

What does that even mean? DOCSIS is a point-to-multipoint network of one CMTS and several modems. All traffic happens between modems and the CMTS. Where would the purported “far more bandwidth” be hiding?

How does that help at all with the peak capacity of a given physical network segment? That’s like saying “the key to increasing the total capacity of a road is to add more cars to utilize all lanes”.
If you use all physical uplink bandwidth of DOCSIS yourself by hypothetically “using more modems”, nobody else on that segment gets anything.
