Re: bhyve VM not getting as much upload bandwidth as the host

1) You can try with Ubuntu 23.04. But are you using VirtualBOX ? Don't use
it,anyway. Bhyve is much better.
2) VMWare Workstation can't be added to the equation,because it does not
run on FreeBSD. Maybe you mean VirtualBOX.
3) You can try with another FreeBSD version that you install on a different
machine ?
4) You can try to configure the network settings on the host os (FreeBSD
13.2-RELEASE) in a different way. Maybe there is some error there. Follow
the Patrick M. Hausen's suggestion. He could be on the right track.
