Electron CPU usage

[pedroken]

Guys, same problem here.
Hardware : BCM2835
Revision : a22082

I just realized something. I’ve installed the MM in a clean Jessie. Results were:

I have an old backup from my first attempt with the MM, and the results (with same few modules) were:

But after 3 hours, look what happened:
A severe memory leakage. I tried with only the default modules, same thing happened. After sometime, the MM crashed. On screen log was showing free list.h:118 Memory corruption chromium.

I`m sure that the version of MM is different from one and another. Someone can tell me how can I see this? Thanks!

PS: Great initiative, @Mykle1 !

I’m just trying to get to the root of this problem. I may never figure it out but I will certainly try.

Nothing ventured, nothing gained.

@pedroken I think this can because the Electron version. Can you tell us what version is for two case.

You can see into the file node_modules/electron/dist/version

Thanks for getting involved here. Just for reference purposes, my Electron version on my Pi 3 B is v1.4.15

Sorry for the radio silence, it’s been busy lately.

I can see what electron version I’m running tomorrow night, and I’ll try and change it to the same version you seem to be getting good performance on and report back.

No worries, mate. Now that @roramirez is looking at this we may find the answer sooner than later.

[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.

[djsunrise19]

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.

[Mykle1]

@djsunrise19 said in Electron CPU usage:

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!
