Problem with vmbr0, slow upload, PVE 8.2.2

[gmce]

Hail to everyone, i have a strange problem with a new proxmox ve 8.2.2 server.
The machine is a Supermicro server with 2 Intel 1Gbe.

Everything is fine but the upload speed, it is very slow. My wan is FTTC with 80Mbit down 40Mbit up.

Here is some info:

All the Windows base VM, with vrtio, shows ethernet card with 10000 speed

The upload to the external PBS is unusable.
