    The capacity is certainly large enough. I don’t know if the U1 designation has anything to do with it. There is a recommended SD card list somewhere. Your free space is more than adequate, assuming you expanded the swap file during installation of the OS, or something like that. If stylelint was a warning, and not an error, then that shouldn’t affect performance. I know, all of this doesn’t help you, so . . .

    A few more thoughts. Are you running Raspbian Jessie? Lite? Are node and npm up to date?

    I know it’s a hassle, but I always suggest a clean, MANUAL installation as opposed to troubleshooting, which could take hours, or days. Some people have had troubles with the automatic installer. That’s just my opinion, for what it’s worth.

      @wtidwell Can you share the configuration when did you get a big CPU usage?

      What version are you using?

        Looks like I’m running Jessie and my SD card is on the recommended list so I’ll try a manual reinstall.

        Thanks for all your help!

          I just did a full clean install of everything including Raspian and I had to install stretch instead of Jessie but everything else installed smoothly but I’m still having this lag.

            2 clean installations, 1 with Jessie and 1 with Stretch and the same issue appears? Unless some step is missing with the OS or MM then I’d hate to assume you have a hardware issue. I really need to get a spare Pi3 so that I can troubleshoot more effectively. I’m only on a dev machine at the moment.

            Perhaps @roramirez has some input here

              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!
