Electron CPU usage

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!

Perhaps @roramirez has some input here
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?

@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.
-
@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.
-
@Mykle1 Don’t worry about it. You provided the information. :) But if you want to do it anyway, do it via SSH instead, you need to have more “screen-space” to fit all the information at the same time. Check my screenshot. The number of columns and rows are much higher. :)

A quick google search reveals that the Pi is mainly manufactured in Wales, UK. However, they are also being made in China, and now Japan. I can’t help but wonder if there is some small difference that would affect performance on those made in the UK and those made elsewhere

@Mykle1 Lets see…
Do (in SSH): cat /proc/cpuinfoPaste the result from hardware and revision… :)
Hardware : BCM2835 Revision : a02082I think it’s the “last” revision that is important.
Pi 3 Model B 1GB a02082 (Sony, UK) Pi 3 Model B 1GB a22082 (Embest, China)Mine is from UK it seams. :)

Here it is. It appears that mine is also from the UK. How about the other info? Does it match up to yours?
