@wtidwell True :)

@djsunrise19 I noticed that you have had this problem for wel over a year now. Damn. I don’t understand how it doesnt work properly… Used Noobs to install Rasbain, used auto install from MagicMirror homepage, nothing else, yet it doesn’t work.

Yes, but today, after

git pull && npm install

it becomes totally unusable. My “seconds” refreshed every 15 seconds, 320% CPU usage… I don’t know.

:( …has anyone here tried another PI. I am considering to buy another one.

I have two of them. The second Raspi 3 (I bought them at the same time) works better. But, as everybody can see, while an animation is working, there are 45-55% peaks (one animation in newsfeed). I don’t think, that this should be.

@TiemenMoesker I tried two pies with exactly the same result. My spikes are way higher than 55%, on the order of max processing.

I have a very stupid question.
In my new ATB, transition animation caused CPU usage around max 70%.(by nmon. htop shows less than that… around 30~50%). Without transition, near 10~20%.
But… I had not felt the performance issue before this thread. Will it be a real problem? I’m not an expert, but I think, temporally CPU usage could be high than we’ve thought. Should I really worry about this?

Hm, okay. But that seems to be a little bit weird. Imagine there are f.e. 8 modules. 3 of them make a fade at the same time (compliments, feed and calendar / netatmo, …). Then max processing is over 100%. Thats the problem in my first screenshot. 320% max cpu. This can not be right.

My ATB is coming today. I’ll made a new installation with all my modules and settings from my actual raspi. I’m very excited and I’ll give a report.

All in all it seems crazy to me, that those transitions are so cpu heavy. And in some cases (look at those nmon screenshots here) the cpu load is way to high and the mirror becomes unusable. So in that case, we should worry about that.

The was originally @Snille idea!

Run in Pi3 terminal (or in SSH): cat /proc/cpuinfo
Compare hardware and revision… :)
Hardware : BCM2835
Revision : a02082

Pi 3 Model B 1GB a02082 (Sony, UK)
Pi 3 Model B 1GB a22082 (Embest, China)

Does anyone with Hardware :BCM2709 have this problem?

Does anyone with Hardware :BCM2835 NOT have this problem?
