Electron CPU usage

Yeah I’d hate that too. =/ gonna try another clean install but this time of Raspian lite. I guess I can try a new SD card as well.

@Snille
That’s what mine looks like now with only default modules. And it spikes all the time.

For what it’s worth:

Here are my screenshots from my Pi3 mirror, via VNC, as of this morning, August 21, 2017
at 8:26am New York time. You can clearly see that Magic Mirror is running. It’s minimized
in the top Menu Bar so I could run Task Manager for this test. I marked the significant
details with red stars. This is on top of a standard Raspbian Jessie installation that was
done in January, 2017 and Magic Mirror version 2.1.0. It has been running this way for
8 months now, without a hitch. These screenshots were done with all of the below modules
running. I also included a screenshot of my system stats to show the temperature of my Pi’s
CPU and my system load, as they both may relate to performance and throttling issues.

Modules running during test and screenshots.

@Mykle1 Can you do a screenshot from a terminal running nmon?
If you are ok with that… Here is how to do it.

Open a terminal (or log in via SSH).
Install nmon (sudo apt-get install nmon).
Open nmon by just typing “nmon”. :)
Press “t”, “l” and “m” to get “task list”, “longer term CPU averages” and “Memory & Swap stats”.
Press + to increase the update rate.
Let nmon fill the “CPU” meter and take a screenshot. :)
Press “q” to quit nmon.
Good thing about nmon is that you can use it from ssh (via putty). :)

Thank you!

I think I did this correctly and I think you wanted a screenshot of each, so here they are. How do my stats look?

Yeah, you gotta try something to eliminate all possibilities. Let me know how you make out. Good luck!

I just made sure I updated to electron1.7.5 and it’s still chugging like before. I got some errors aboutHere is my nmon reading as well.

It can be frustrating. Hang in there. We’ll try to get you sorted or at least find out what the issue is so it can be corrected.

Now, let me look at your nmon

Edit: Ouch! :-(

Snille

@Mykle1 Thank you! :) You can actually get all three on the same “screen”. :) But what matters is that your CPU is hovering around 5% and mine (ours) are hovering around 20%x2… That is strange.

@wtidwell Are you rinnung a “lite” version or a full version of the OS?

wtidwell

@Snille
I’m running a full version. I intend on reinstalling Raspian lite when I have some free time if I can’t troubleshoot it until then.

When I was installing electron, I tried to install it globally with the -g command like it suggested in the electron readme. However it said I didn’t have permission and I tried to repeat it with sudo and it still said the same thing. Not sure if that means anything significant. I did get it to install non globally with no errors but I dunno if that may be my problem.
