Electron and high CPU usage on Raspberry-Pi 3
-
@alborzs - Which modules do you have loaded? The basic Magic Mirror isn’t terribly resource intensive. But some modules really give it a workout.
-
@bhepler, is there a way to find out if/what module might be the cause of the extensive CPU usage? Other than the default modules, I only got MMM-Netatmo and MMM-ResRobot.
-
@alborzs - other than the hard way, no. Remove all of the modules and then add them back one at a time with an eye on your CPU usage.
The other thing to double-check is to make sure that you have one of the OpenGL drivers active. The regular one or the fake one, it doesn’t really matter which. The non-OpenGL driver uses a lot of CPU time.
-
@bhepler, that did solve the problem, One module was causing the issue. Thanks.
-
@alborzs Which module caused it? Sure hope it’s not ResRobot as that is my next add-on.
