How is the Internet speed distributed between processes?

Question

System administration

I have several gigabyte uTorrent and Yandex Disk files downloaded via a 100Mbps wired connection, and web pages are loaded in parallel in Ya.Browser.
uTorrent takes everything it can. When he finished, J.D. began to take over the entire Internet. Only after that it became possible to use the browser.
How is the Internet connection distributed and why is it not even?
Process priorities are the same.

How is the Internet speed distributed between processes?

No way.
Packets are queued in the order in which they are received, first come first in the queue.
Only a piece of the queue limited by your tariff will get through the provider's interface. If there are more packets in the queue than can get through the interface, then all those who did not pass are destroyed.
That's all.
Install a router that can prioritize - give preference to one or another type of traffic. Or specify in the application settings - like uTorrent restrictions, so that they do not clog the entire channel.

Process priorities are the same.

Did you look in the task manager?
The priority of a process determines how much CPU time it gets and nothing else. It does not affect network transmission in any way.

Answer 2

Trite, but the speed is distributed according to the application settings :)
