Hi guys. I'm running libreelec 9.2.1 on raspberry pi 4b 4GB. I also have the docker addon installed with home assistant and nginx letsencrypt. when i run the top command, i get this results.
When idle, kodi.bin cpu usage is about 40 - 50%

I'm not sure how this works. Is that how it should be? is 40% cpu usage on idle too high?
Best regards,
Anand
