0xFeedBeef I can’t speak for the OP, but when ATV+ had that issue for me, it slowed down to under 50 KB/s and has dipped to nearly 0. Today I got over 40 MB/s, which has been pretty much normal since I switched my DNS.
I’m on 3 GB fiber hard wired with Cat 7, but limited by a 1 GB switch and network card. 10 GB hardware is expensive, still.
