For any of this to make a difference you should disable µTP in your torrent client, or make it prefer TCP over µTP.
Just as a caveat, people disabling/throttling µTP may want to manually set appropriate global rate limits (upload/download bandwidth) otherwise it’s possible the torrent client will actually hit the maximum upload/download limits of the ISP or router forcing everything else on the network to slow down/time out during other internet usage. You’re obviously more advanced so you already know all this :)
Mainly it’s extra info for noobs messing around with their settings, often times noobs mess around with settings, disable things, etc. & then wonder why their torrent client keeps “crashing” their internet :P Making changes to µTP should be more of a last resort IMO.
µTP itself is a pretty big topic, there are a fair amount of people testing different settings in the qBittorrent / Libtorrent Github Issues but I’m not sure there’s even a consensus on a proper default setting. e.g. qBittorrent’s devs specifically chose different µTP defaults vs the Libtorrent library’s own defaults. qBittorrent defaults to having µTP enabled with preferring TCP (throttles µTP), Libtorrent defaults to having µTP enabled with peer_proportional (does not throttle µTP). The qBittorrent default is reasonable though I wonder if the Libtorrent default is the more “correct” approach but that’s certainly up to much debate. In both cases µTP is never disabled completely.
With my own testing I tend to keep settings at Libtorrent defaults just to observe behavior, with mainly private tracker peers I’ve noticed at least ~60% of my incoming connections are from µTP peers so at least for me it seems reasonable to keep it enabled.
