Hello Phillipe
To my non-expert eye the "dev-loop" events seem to be making a difference between 18.04 and 20.04. The "dev-loop" events are snap packages starting up, as far as I know.
That being the case, I would not expect to see much difference between 20.04 and 20.04.1, as more of Ubuntu-Mate is now being delivered as snaps I believe (I may be wrong there).
