Does CPU Usage correlates with Firmware version

[Beno]

Not that I have noticed.

Are you running Node-RED?
If so, can you try this flow on each and see what process is using the CPU.

Get 'top' process data into groov via Node-RED

This flow uses the exec node to run a top command that fetches system processes and their resource usage, then uses JavaScript to sort the data for output to a groov data store, either as formatted strings or parsed decimals, or both!
