Question is very simple. If you are using a very unefficient protocol like https, which relies on heavy buffering, all is reduced to the quality of client (the webplayer most likely). So, which switch/router/cable to use is no sense question.
If you are changing router/switch/cable and you hear big differences, logic says you are using a UDP like protocol, or the https client is extremely poor.
