Electron CPU usage

@wtidwell said in Electron CPU usage:
I did remove both compliments and news feed both together and individually to see if it was one particular module but it seems to be both causing problems.
Well, I’m fairly certain it is neither one of those modules. You’ve got something else going on there. The Pi3 can easily handle the default installation, and more.
What size SD card are you using? What speed is the SD card you are using? Is there anything else on the SD card other than the OS and the MM software? How much available space is on the SD card?
-
It’s a Samsung 32gb microsd. It’s Class10, u1 which I was wondering if that may be a problem? It says I have 22.9gb free out of 27.9 total.
Also I tried to reinstall electron and it said there was an unmet peer dependency for styleint. So now I’m trying to figure out how to install that.
Edit: got stylelint installed but it’s still laggy.
-
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.
