    Hmm… I always thought this was a normal behavior? Electron always runs pretty high on my RPI Mirror. This is my “task-list” using nmon on the RPi (via SSH) with basically nothing on the Mirror Screen but as you can see Electron is pretty active. :)

    I do have quite a lot of active plugins of course…

      Yeah I’d hate that too. =/ gonna try another clean install but this time of Raspian lite. I guess I can try a new SD card as well.

      @Snille
      That’s what mine looks like now with only default modules. And it spikes all the time.

        For what it’s worth:

        Here are my screenshots from my Pi3 mirror, via VNC, as of this morning, August 21, 2017
        at 8:26am New York time. You can clearly see that Magic Mirror is running. It’s minimized
        in the top Menu Bar so I could run Task Manager for this test. I marked the significant
        details with red stars. This is on top of a standard Raspbian Jessie installation that was
        done in January, 2017 and Magic Mirror version 2.1.0. It has been running this way for
        8 months now, without a hitch. These screenshots were done with all of the below modules
        running. I also included a screenshot of my system stats to show the temperature of my Pi’s
        CPU and my system load, as they both may relate to performance and throttling issues.

          @Mykle1 Can you do a screenshot from a terminal running nmon?
          If you are ok with that… Here is how to do it.

          1. Open a terminal (or log in via SSH).
          2. Install nmon (sudo apt-get install nmon).
          3. Open nmon by just typing “nmon”. :)
          4. Press “t”, “l” and “m” to get “task list”, “longer term CPU averages” and “Memory & Swap stats”.
          5. Press + to increase the update rate.
          6. Let nmon fill the “CPU” meter and take a screenshot. :)
            Press “q” to quit nmon.
            Good thing about nmon is that you can use it from ssh (via putty). :)

          Thank you!

              I think I did this correctly and I think you wanted a screenshot of each, so here they are. How do my stats look?

                Yeah, you gotta try something to eliminate all possibilities. Let me know how you make out. Good luck!

                    It can be frustrating. Hang in there. We’ll try to get you sorted or at least find out what the issue is so it can be corrected.

                    Now, let me look at your nmon

                      @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?
