OPNsense Bare Metal vs Virtualization (sh.itjust.works)

Looking for some advice / recommendations / considerations on running OPNsense on bare metal vs virtualized, and if virtualized how best to do so.

I currently have OPNsense running bare metal on a Protectli FW6E Vault, with the following specs:

Intel i7-8550U CPU @ 1.80GHz
120GB mSATA (1% utilization)
16GB RAM (6.5% utilization)
6 Gigabit Ethernet NIC ports

The Vault running OPNsense is the primary firewall and router, any wireless devices connect through a dumb AP running OpenWRT. Connected over Ethernet I have a RPi running HomeAssistant OS (would probably also move to virtual if that's the chosen direction) as well as a TrueNAS setup.

How much of a performance hit would be expected running in some sort of container vs the current bare metal setup? Are there any other concerns with running the main firewall / router virtually vs bare metal to take into account?

I just found my order confirmation email. Mine is model FW4C (now superseded by the V1410). Purchased almost two years ago.

I'm very satisfied with mine. Nearly 100% uptime, except for occasional reboots after major system updates.
