HA high CPU usage/spikes since 2024.11.x update

[mihaicristianpetrescu]

Describe the issue you are experiencing

Home Assistant Yellow with RPI CM4 8GB RAM - so maxed out.

Since updating the supervisor to 2024.11.x and then the core to 2024.11.x, Home Assistant CPU usage started going up, it spikes a lot and the interface loads slow - in comparison before these update the CPU was pretty much sitting flush between 10-20-ish%, now it is constantly above 20ish% with spikes to 40%.

No other updates have been performed or other new add-ons, HACS installs, even new configuration or devices added. Just the supervisor and core updates.

I've downgraded the core to 2024.10.4 and it somehow helps getting the spikes down a bit, but the system is still running slow. Unfortunately supervisor cannot be downgraded otherwise I would have tried that as well.

Not sure what got broken but there's definitely something seriously broken, either in the supervisor update or the core update. There is a difference in CPU spikes between core 2024.10.x and 2024.11.x, but there still are spikes in comparison to the before core 2024.10.x and supervisor 2024.10.x.

I've installed Glances add-on and saw python-3 being the one process that's spiking and in return increasing the homeassistant docker CPU usage.

I've tried every single core 2024.11.x update so far and not 1 of them fixes the problem, have been constantly going back to 2024.10.4 to have a somewhat semi-responsive system.

Seems like this might be more of a supervisor problem than a core, because there is still high CPU even on older core (Ex 2024.10.4), but with the latest available supervisor (since it cannot be downgraded to test out) 2024.11.2.

What type of installation are you running?

Home Assistant OS

Which operating system are you running on?

Home Assistant Operating System

Steps to reproduce the issue

Simply start HAOS and notice how the CPU start spiking up constantly going to 30% or more. Spikes are a whole lot more worse on newer core 2024.11.x than on 2024.10.x but they are still there. Before updating the supervisor things were running well - as far as I read there's no way to downgrade the supervisor otherwise I would have tried that as well. Core was updated after supervisor.

Anything in the Supervisor logs that might be useful for us?

Doesn't seems so.
