Electron CPU usage
-
The capacity is certainly large enough. I don’t know if the U1 designation has anything to do with it. There is a recommended SD card list somewhere. Your free space is more than adequate, assuming you expanded the swap file during installation of the OS, or something like that. If stylelint was a warning, and not an error, then that shouldn’t affect performance. I know, all of this doesn’t help you, so . . .
A few more thoughts. Are you running Raspbian Jessie? Lite? Are node and npm up to date?
I know it’s a hassle, but I always suggest a clean, MANUAL installation as opposed to troubleshooting, which could take hours, or days. Some people have had troubles with the automatic installer. That’s just my opinion, for what it’s worth.

@wtidwell Can you share the configuration when did you get a big CPU usage?
What version are you using?
-
@Mykle1
Looks like I’m running Jessie and my SD card is on the recommended list so I’ll try a manual reinstall.Thanks for all your help!
-
I just did a full clean install of everything including Raspian and I had to install stretch instead of Jessie but everything else installed smoothly but I’m still having this lag.

@wtidwell
2 clean installations, 1 with Jessie and 1 with Stretch and the same issue appears? Unless some step is missing with the OS or MM then I’d hate to assume you have a hardware issue. I really need to get a spare Pi3 so that I can troubleshoot more effectively. I’m only on a dev machine at the moment.Perhaps @roramirez has some input here

Hmm… I always thought this was a normal behavior? Electron always runs pretty high on my RPI Mirror. This is my “task-list” using nmon on the RPi (via SSH) with basically nothing on the Mirror Screen but as you can see Electron is pretty active. :)
I do have quite a lot of active plugins of course… -

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.

@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!
If you cant find it, make it and share it!

What version of electron did you is installed in the system?

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

@wtidwell said in Electron CPU usage:
I guess I can try a new SD card as well.
Yeah, you gotta try something to eliminate all possibilities. Let me know how you make out. Good luck!
-
@Mykle1
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.
Imgur.com/np2mv54I don’t know what to make of this haha

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! :-(
-
@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?

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.
-
@wtidwell Nah, I’m running the “lite” version of Jessie… So it’s not that… I did not do a separate install of electron actually. I used the “install-script” from MM at the beginning… It’s goning to be interesting to see if you get any better results with another SD card…

@Snille
Speaking of hardware, and this may be a dumb question, but any chance the mouse and keyboard are causing this performance hitch? I just plugged in the ones on my desk which are the corsair strafe and logitech g600, both more intricate than normal pnp mouse and keyboard… -
@wtidwell Nope, I don’t think so. I have not had any keyboard nor mouse connected since I installed it. :)

I followed your directions but only one appeared at a time. I’ll try again later if you want me to. Getting ready for work at the moment.
