I had the following in sysctl.conf:
net.link.tap.up_on_open=1
net.link.bridge.pfil_member=0
net.link.bridge.pfil_bridge=0
net.link.bridge.pfil_local_phys=1

So I only did:
sysctl -w net.link.bridge.pfil_onlyip=0
sysctl -w net.link.bridge.pfil_local_phys=0

Nothing has changed for the linux VM.

Windows11 VM is getting download/upload speed of 40Mbps/37Mbps while a Debian12 VM is getting download/upload of 37Mbps/45Kbps.
Maybe there is an issue with the Linux itself?

I never had this solved. Even my FreeBSD guest on FreeBSD host with VirtualBox is slow as few hunderds kB/s It was like 10Mbps with Bhyve. I only use VMs for testing but installing packages is always so slow. So you are not alone. I would really like to know how to improve the network speed with virtualized environment.

Kind regards
