I know it’s not how it’s supposed to be but I use a Pi Zero running Stretch lite. I start the Mm using „node /serveronly“ in a .sh script and launch chromium afterwards.
Typing in these commands works perfectly fine. Everything takes some time to boot, but then, it just works.
To start it after bootup, I use Pm2. It takes some time but it works. The problem is: the Pi‘s CPU is at 100 % all the time since node /serveronly runs 4 times and each needs between 15 and 20 %.
How can I fix that? Any idea?
