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.

@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
