pfSense 2.7.0-RELEASE (amd64) on FreeBSD 14.0-CURRENT high CPU usage?

I've "isolated" and "pinned" one core of my 16 core intel CPU for pfSense, and it seems to be working flawlessly except for a perhaps cosmetic defect? 

 

Nothing else is isolated or pinned.  The CPU usage on the pfSense dashboard is always in the range 1-16%, but the CPU usage for that one core running the VM on the unraid dashboard is usually in the range 10-60%, sometimes peaking to 100% for a few seconds.  I'm wondering why the big discrepancy?  I understand they're measuring different things in different ways, but why to that large an effect? 

 

The highest usage (100%) seems to coincide with my GPU doing transcodes for Jellyfin or tdarr, but not always -- and neither of those are using much internet bandwidth so that seems weird too.

 

Any ideas?  Should I even care?

Nope.  I just gave it the other core of the pair so it doesn't look "starved" on the usage graph,  With two cores it barely ever gets above 5% usage.  It's a waste, but makes me feel less angst.
