      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

        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.

              Well, that’s good news! :^)

                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.

                  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.

                      Today, I tried a few things, too. Perhaps my results could be helpful for us. Sorry, this will be a long post ;). I have following the devices:

                      • Raspberry 3 Model B - my standard mirror device
                      • Asus Tinker Board
                      • odroid C2 (ARM64)

                      Software Versions MM:

                      • MM v2.1.2 on all devices

                      Electron Versions:

                      • Raspberry 3 Model B (v1.6.11)
                      • Asus Tinker Board (v1.4.15) but v1.6.11 works the same
                      • odroid C2 (ARM64) (v.1.8.0 - because of the x64; I uninstalled spectron, because there is no x64 support)

                      Configs:

                      • Standard (Calendar, Compliments, Newsfeed, Clock)
                      • MyConfig (Calendar, Compliments, Newsfeed, Clock, Todoist, Sonos, Netatmo, WheaterUnderground, Stocks, Reiseauskunft, Strava); here, cpu usage is a little bit higher, but the behaviour is the same.

                      The 100% usage topic seems to be a electron problem and I think it can be solved with some downgrades of MM2 and electron. v.1.7.5 seems to be bad. Whatever, here is what I found out:

                      1. nmon with the ATB (v1.7.5 electron here) and default config:
                        0_1504730980288_atb_defaultconfig-2.1.2-MM-1.7.5-elec.png
                        CPU usage while transitions is very high. Lagging!

                      2. nmon with the ATB (v1.4.15 electron here) and default config:
                        0_1504731051428_atb_defaultconfig-2.1.2-MM-1.4.15-elec.png
                        CPU usage is better but, to be honest, way to high for transitions (cpu peaks). And still some small lags.

                      3. nmon with the odroid and default config:
                        0_1504731421342_odroid_defaultconfig-2.1.2-MM-1.8.0-elec.png
                        The best result. but still peaks while the transitions. Some lags here, too.

                      So, here is my actual config:
                      4) nmon with the Raspberry 3 Model B and MyConfig:
                      0_1504731971062_raspi3_mauroconfig-2.1.2-MM-1.6.11-elec.png
                      Same here, still lags.

                      The last thing I tried was very interesting. I opened my chromium on the ATB and put the webadress from my Raspberry 3 Model B device in it. So I openend that Rapsberry 3 Model B MM2 on my ATB. And that happens:
                      0_1504731554810_atb_mauroconfig-browser-raspi.png
                      Absolutely smooth, no peaks at all.

                      BTW: My Raspberry 3 Model didn’t have any more cpu usage while that process.

                      Can anybody tell us, WHY?

                        As I see, rendering engine of electron seems to be the reason of whole of thing. Electron has its own v8 and renderer. I doubt it goes worse on some late version. I don’t know why, but there is few things we could do.

                        Report this to electron, wait a patch. Or downgrade or… turn off the animation.
