Just reinstalled to give it a try. When the printer is idle and does nothing it is ~1% CPU load.
However, when I open the Obico webpage and login or open the mobile app there is a short spike of up to 20% CPU load!
Same happens when refresh is pressed in the app.
When it is printing the CPU load of Obico toggles between 1 and 10% (seems pretty high to me), even when I don’t have the Obico page or app opened.
