Electron CPU usage

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

@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?

My hardware is also BCM2835 revision a02082 , just like Snille. I have another micro SD I think floating around somewhere in my house, I’ll try and do a clean install of rapsian stretch lite on it tomorrow and use the auto install script on that and see how that goes. Fingers crossed I just got a crappy SD card or something.

How did you make out? I’ve been thinking about this issue since you started the topic. I did quite a bit of googling and there are a number of instances where people had trouble (not with MM) with performance, and heat. In many cases, those people determined that their Pi’s were faulty, after much time, frustration and troubleshooting. In those cases, they had their Pi’s replaced and the problem was solved.
I hope the new SD solves your problem but I have my doubts about that. Please keep me informed and good luck.

@Mykle1
Well I ordered a new pi 3 on Amazon and did a fresh install it’s the same thing all over again. Every time the text changes on magic mirror it maxes out my cpu. And it’s starting to overheat as well and I didn’t even change any overclock settings.Quite infuriating honestly. I don’t know what I’ll try next.

Oh man, that sucks. I’m sorry to hear that. I’m at a lost here. Really, there is no logical reason for that to happen

@Mykle1
My last ditch effort is to try a new SD card. The card it came with is a SanDisk 32gb card and it’s just a plain black card and I have this otherone which is a SanDisk ultra 32gb card so maybe that does something. -
I am certainly rooting for you! I think there was/is a walk-through on preparing the SD card, formatting and such, although I don’t remember where. It’s been a long time.
The best of luck to you. Please keep me posted

@Mykle1
Just to rule out one more variable: the pi 3 should be fine running at 1080p yes?
