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

You should isolate the problem. You could make some tests to understand
where the problem is. So you could create a matrix that can help you to
create all the possible cases to analyze if the problem is :

1) within your specific vm only
2) in any vm you create with virtualbox and linux (which distro ? changing
distro may solve the problem)
3) on the network config of the host os (freebsd) (what version ? changing
version may solve the problem)
4) any other combination that can exclude variables
