Comment on virtualizing OPNsense is....not going great

The performance drop from virtualizing nics shouldn’t be nearly as big. How are you passing the vlans to the VM? are you passing all over one virtio nic or one virtio nic for each.
The setup I ran for multiple years was basicly a bridge interface on the host for each vlan and a seperate virtio nic to the opnsense VM for each, I got almost 10 gbit/s like that with 8gigs of ram for opnsense and 4 or 8 cores (I cant remember) with hyperthreading of a 2nd gen epyc.

I’m not running an epyc. Way too spendy for me. I was using direct attachment pasture but that was failing over to Macvtap because this motherboard sucks and the IOMMU/ACS shit only actually works on the GPU slot and 1 M.2 slot.
Supposedly I can use IOMMU with an i350 and that will work good enough but I’m not certain if this as it’s not the same as a direct passthru so I’m worried I’ll have similar issues.
I’m also reading the i226v NIC I have is kind of ass anyway.
