Dear Maintainer,
I intalled kodi a few days back in order to access all my media from a TV.
I executed and configured it using its GUI. Then I stopped it and run the
standalone version from a systemd unit in order to have it running all time.
I noticed that while nobody is using kodi from my TV, i.e., during nights, the
CPU usage is constantly about 8-12% for kodi.bin process.

Why? Is there anything that can be changed on the configuration in order
to stop this high CPU usage?

Just for reference, the CPU is Intel(R) Xeon(R) E3-1225 v3 @3.20GHz.

Thank you,
Giuseppe

Hi Giuseppe,

Thanks for report! The reportbug contents was probably truncated, as I see
no information about hardware, architecture etc.

What is your device specs?

Hello Vasyl,
I am trying kodi on a DELL PowerEdge T20, CPU E3-1225 v3 @3.20GHz, 32Gb of
RAM, Debian GNU/Linux 12 (bookworm).

Thank you,

Hello Vasyl,
here is some information and a stack trace of the kodi thread that keep
consuming CPU.

From what I understand, the problem is in the renderer code, but I am calling
kodi in standalone, so I think the renderer should not used at all.
