Why is the internet slower in a Hyper-V virtual machine?

Question

System administration

Greetings.
Tell me why speed can be cut in a windows 10 virtual machine on Hyper-V? I raise it through the switch, on the main system the speedtest shows a stable speed of 100 mb / s sending and receiving, and the virtual machine is either 5 or 10 or 30 or even 100 kilobytes ... it jumps incomprehensibly. Why might this be?
At the same time, 10 virtual machines are running, if it were the congestion of the Internet channel, then a drawdown would be visible in the main system, but it is not there, everything is stable. There are no proxies in virtual machines, there are no loads during the test either.

Answer 1

Try to play around with the network card model that is installed in the virtual machine. There are two options, if my memory serves me, switch between them.

Answer 2

Maybe it ?
