Unbelievably slow inter-vLan traffic in KVM OPNsense after 21.7->22.1 upgrade

Hi all, at my parent's house I have setup OPNsense as a KVM guest in a small Linux homeserver. Two Intel ethernet adapters are directly mapped from the linux host system to the OPNsense instance. One is uplink and one outputs 4 trunked vLANs which are then distributed thoughout the house and to an AP via a switch. (separate segments for trusted and untrusted server devices, parents and kids)
The KVM virtualized Firewall always wasnt the fastest, but for the task at hand ("fast enough for netflix") the vLan to vLan throughput was good enough at about 100+MBits.
However, after updating to 22.1, sending data from one vLan to another through the OPNsense router (e.g. streaming from fileserver to tablet) has come down to a mere crawl, maxing out at about 300-500kilobytes per second, with the permanent rate more at the lower end of that range. Once I swap in the backup image of 21.1, all is back to normal.
I have not changed any settings beyond the update. What could have gone wrong? Any ideas where to begin looking? Although I am quite proficient as a linux user, my BSD experience is limited and outdated.

Have you separately enabled the parent interface of each of your vlans? New ‘requirement’ for 22.1.
