HomeAssistant performance concerns

Hello All,

I have HA installed on VMware on old Lenovo T430 laptop. When I’m generating a graph of some entity for long period of time (like month for example) it takes really long time to generate (around 1-2 minutes). That is OK - I get it - but at the same time CPU utilization of HA virtual machine during this graph generation process is below 5%. Why HA is not utilizing the whole power of CPU while doing this?

For example generating this graph took more than 1 minute while CPU utilization was close to 0%:

BTW - it’s the ONLY Virtual Machine on this laptop. No else VM is running there.


Even when I’m creating backup of HA CPU utilization is like 25% at it’s peak.
