If you have a PC downstairs and another PC (or a NAS or ...) upstairs and the path between them goes through Powerlines, how fast does a large file transfer go between them (assuming both ends have gigabit ethernet capability)?
How long is a piece of string?
If someone else is downloading over the powerline at the same time, less good.
It's fast enough for me to watch stuff on Prime or my wife to watch Eurosport on the FireStick, via WiFi. Our NAS is not fast, but is that the powerline or the NAS? I'm also not running the latest powerline stuff, but a set of secondhand TP-Link devices limited to 600Mbps (AV600) rather than 2000Mbps for a recent set.
Of course you could just watch youtube.

TV isn't a demanding test, and the advertised speeds are just marketing theoretical maximums, not real world.
It's absolutely possible to measure the length of the string, as the video shows, albeit with, IMO, disappointing results. Indeed I did the same many years ago with a pair that TalkTalk sent me. Doing file transfer over my then Fast Ethernet (100Mb/s) would run at pretty much that speed, but doing the same though the Powerline adaptors plugged into the same double socket slashed that to only 40Mbs/s.
Relatively better than in that video though where, despite having double-Gigabit Powerlines, they only managed 30ish% of the full Gigabit. Mind you, he is testing the TP ones, which responders here don't seem to have a very high opinion of....
