While it’s true that i2p torrents are slower than clearnet torrents the speed is not really as bad in my experience. I would say i can download most shows, movies and files in general in 1-2 days max (I know that is slow in comparison, but its OK if you are just building up your library, atleast for me). On average i would say a “normal 1080p movie” finishes in 5-6 hours (In my experience). The bigger Problem is sometimes the lack of torrents and seeders, although this is getting better
