It is a feature for stupid people and it causes all kinds of strange issue for some. What it tries to do is make people think it will fix delays related to prioritization of traffic. What it fails to clear state is that it can have no effect on traffic from any other device. So if you have a second PC overloading your internet connection it can not fix it.
What it can do is make certain traffic on the machine itself run better. So if you are running torrent and playing games it can give the game traffic priority. This is why it is a feature for stupid people. Instead of just not running software that impacts my game I will load even more software to try to fix it.
