Electron CPU usage

[pedroken]

@roramirez , the version in the high CPU scenario is v1.7.5. The animations are sluggish, even with only the default modules.

The version of the lower CPU consumption but strange memory leak is v1.6.11.

Thanks!

I’ll try to use @Mykle1 's version of electron. I`ll google it (how to). Never did it.

@pedroken
I also have v1.7.5 and I do have the problem.
Didn’t find out how to downgrade so I’ll waiting for your results :-)

@mibafz00
Forgive me if this is dumb, but couldn’t you just delete the electron folder and reinstall a specific version with

Npm install electron@version?

Some mention here of high CPU usage. Maybe electron IS the culprit

Input from my side: I checked the issues with electron 1.8 beta. Same problems.

Well, you let we know if with that version of Electron is fixed the CPU usage. You can modified by hand the package.json to say to npm what version to install of Electron.

My two cents again ;): My electron pakackage.json version is v.1.6.10. I made a downgrade to v1.4.15. Code says “invalid”. But the installation seems to work? Do you guys know, where I can check the installed electron version?

No effect. 55% CPU and very sluggish (256MB GPU Memory):

You can see the installed version in this file MagicMirror/node_modules/electron/dist/version

[djsunrise19]

@Mykle1 Thanks. Yes, v1.4.15.

Thanks. Yes, v1.4.15.

I just had a thought (miracle). What version of MM is everyone using?

My Pi3 B mirror is running MM version 2.1.0. I’ve had no reason to update it. It’s rock solid

I had this problems since the new MM2 Version. Very long so. But my version is the newest one. 2.1.2 I think.

uh oh! So you DIDN’T have this problem before the new version?

Hi.

I made a downgrade Electron from v1.7.15 to v1.4.15.
CPU load up to 320% is gone.

Hardware: BCM2835
Revision: a22082
MagicMirror: 2.1.2

@SashMare @Mykle1 my
I also downgraded electron to 1.4.15 and I’m seeing dramatically improved performance!

Do you have some CPU load Screenshots? As I read, around 55% is to high too.

@djsunrise19
Not on hand but I’m seeing in the mid 20’s with newsfeed animations

Well, that’s good news! :^)

[Mykle1]

You guys are both running MM 2.1.2? There has been some mention that this problem arose after the upgrade. My Pi3 B mirror is still running MM 2.1.0. :-/

Just a thought.

[mibafz00]

@Mykle1
Today, I tried the following:

MM 2.1.2 + Electron 1.7.5 --> CPU 100% during transitions

MM 2.1.2 + Electron 1.4.15 --> problem still there, CPU 100% during transitions

MM 2.1.0 + Electron 1.7.5 --> problem still there, CPU 100% during transitions

MM 2.1.0 + Electron 1.4.15 --> problem (probably) gone, CPU 40% during transitions

So i guess you have to downgrade both, MM and electron…!?

I’m curious. What is the CPU load at rest, when no transitions are executing?

In any case, that’s a good amount of testing on your part, and hopefully it will lead to a final diagnosis of the problem.
