Hi all!
If I install HomeAssistant on a multi core system, will it make use of those?
As far as I know HA Core is single threaded, but what about the add-ons and plugins. For example Frigate or InfluxDB - will those be limited to the same single core and share it with HA Core or are they able to make use of a multi core CPU?
Thanks in advance 
Yes
That’s not correct - HA Core is multi-threaded
Oh that’s great! Read the opposite somewhere else.
So I’ll stick to a native HomeAssistant installation and ignore Docker and VMs. Thanks!
I don’t see the link. Even in a VM (if you give the VM some CPUs) or in a container, HA will use multiple CPU’s
Yeah, but I was thinking about installing HA Core in a VM to be able to use unsued cores for other components like facial recognition and NVR. But now that I know the resources will be available in native HA, I do not see a usecase for Docker or VMs. I should be able to use everything from HA by installing the Add-Ons or using Portainer. I thought of VMs as a workaround to be able to use all system resources, but this is obviously unnecessary if the HA OS can do this as well.
You can’t use Portainer on HAOS.
If you’re using HAOS then you have access to add-ons and nothing more. If you want the ability to run arbitrary Docker containers then HAOS isn’t the way.
Why shouldn’t I be able to install the (inofficial) Portainer Add-On for HA?
Because the system will immediately flag it as unhealthy and unsupported and disable functionality.
Is there functionality lost nowadays if your run an unsupported setup?
Depends… do you count the ability to upgrade as functionality 
That was unhealthy, no? Unsupported as well?
Just for curiosity 
Honestly… I don’t run HAOS and I’m not entirely sure what stops working when you deliberately break it
Yeah, I probably don’t need Portainer anyways. Until now I found a working add-on for everything I needed. As long as HA can use all system resources, I’ll be fine.
