What happened?

Bridge network download speed is very slow in the guest

How can we reproduce this?

Use bridged network mode, try running speedtest : it shows only 2 mbit/s, while I can get 1 gbit/s on host.
Reverting to 7.1 improves performance to 200+ mbit/s, not ideal, but it is enough for me to not dig deeper.

None of the suggested workarounds worked for me.
