@royk Hi
Yeah, my bad, i guess when you open an ssh connection it goes up a little bit as you can see on my second screenshot (when you log in), thats why I posted the htop screenshot too, because it didnt match.
Running mpstat showed me the truth:
# mpstat
Linux 5.10.160-rockchip-rk3588 (orangepi5-plus) 06/14/2023 _aarch64_ (8 CPU)
09:00:44 AM CPU %usr %nice %sys %iowait %irq %soft %steal %guest %gnice %idle
09:00:44 AM all 0.25 0.00 0.66 0.07 0.00 0.01 0.00 0.00 0.00 99.01
About 99.01% of idle, or 0.99% of usage . Pretty nice.
