Why is my average load so high?

Maybe the community could help me with this. 

At first I noticed that Homey is stuttering when saying something from a flow. When I took a look to the Forum concerning stuttering and then in the system settings I noticed that the average load of my homey is quite high:

3.72265625 - 2.49853515625 - 1.78857421875
1.30078125 - 1.50390625 - 1.53564453125
1.705078125 - 1.58984375 - 1.56298828125
0.8193359375 - 1.3515625 - 1.48193359375

My Problem understanding this is: Looking in the Developer Settings, there is no app using the CPU (Sonos with a max of 3%)

Could someone imagine why my load is so high, that Homey starts stuttering?

Info: 16 apps installed, round about 80 devices

Thanks
Seraphim

    It could alsof be a flow loop triggering multipie times a second.
    And did you check how much memory is consumed, especially swap? That could point to a badapp and/or memory leak.

    Hello GeurtDijker,

    Let's start with the "hard facts":

    Uptime: 700018 sec
    Swap: 462,41 MB



    Concerning the Flow hint: I installed Homey Logger and can't see anything happen more than once a second.

    Imho a lot of swap for only 16 apps.
    Good point in reviewing with Homey  logger, but  afaik it doesn't show the flow triggers itself. Only the resulting events or other triggers.
    How does it perform some time after restart? And how fast is swap climbing?

    I restarted Homey.

    Swap after Restart: 8.86 MB
    Swap after 1 Min: 16.07 MB
    Swap after 5 Mins: 15.88 MB / 0.8232421875 - 1.9287109375 - 1.38330078125
    Swap after 10 Mins: 15.38 MB / 1.30712890625 - 0.94677734375 - 1.07275390625
    Swap after 30 Mins: 14.41 MB / 2.72607421875 - 1.60400390625 - 1.18408203125
    Swap after 60 Mins: 20,82 MB / 0.86865234375 - 0.51611328125 - 0.640625
    Swap after 120 Mins: 55.01 MB / 0.734375 - 0.6181640625 - 0.6787109375

    Performance seems to bee better, Homey wasn't stuttering within the last two hours.

    Any chance to get known if there is something triggering multiple times a second?

    Update: It's now 17:12 and the Swap is 87,50 with an average load of 1.1181640625 - 0.98779296875 - 1.11962890625

    For what it is worth, I noticed that deactivating several flows had quite some influence on my average load. I have a hole bunch of variant flows for my screens. Different ones for different periods through the year.

    Since we are in fall and winter is coming up, these flows are irrelevant this time of year. I'm happy when some sun comes in this time of year :) I built another very simple flow checking the period of the year (month-from-to). If in that period, disable all other flows. This had quite some impact on the load.
