How to accustom a torrent to use a very fast Internet?

Question

bittorrent

It's about μTorrent, couldn't select it in the tags.
We have ssd and 300/1000 Mbps internet.
Recently, I like to choose torrents, where there are very few hundreds of seeders and a lot of downloading peers. I would like, so to speak, to help hard workers save time, and, well, indulge in numbers in return.
But the torrent still does not stick, which can be downloaded and uploaded at the same time. From his point of view, if you download 20 mb, then you should give no more than 1. (???)
And now I don’t know how to fix this auto-tuning.
The checkbox "Supersid" in the properties of the download itself does not give anything.
Just the return of an already downloaded file can be 30+ mb, if there is a demand.
I did a bunch of Internet benchmarks, can download / give 300/500 Mbps at the same time, solo return 900+.
For example, cloud sends up to 600 to email, up to 500 to YouTube (you can see the limit there), well, where is it, now everything seems to be fast everywhere.
Let's get back to the torrent: all the limits have been removed, but we stubbornly do not distribute while downloading. How to fix?

You don’t have to go far, here’s a stupid screen: a lot of peers, and we just download point-blank, although there’s still 10 MB of reserve for the jump. Or I do not understand something?

Answer 1

For a high distribution speed, you need to disable uTP so that the UDP traffic flow does not gobble up all the performance, and unscrew the disk cache in the settings so that Disk IO does not consume performance, and the data is taken from RAM as much as possible.
