Help me optimize my CPU consumption

[mabed-fr]

What is your question:

Hello,

Today for the first time I had to use my frigate videos for an intrusion into my home.

To my great surprise the videos during detection were unreadable.(grey and slow...) :(

I notice that my CPU load was 8-10 before deactivation of bird eyes and now i have 4-6
I also deactivated the second objective of the trackmix for the moment

Do I really need to change hardware or do you see any areas for CPU optimization?

[NickM-27]

you should provide screenshots of the system page, there is nothing here to tell us what is and is not using CPU

[mabed-fr]

I just added this now.

[NickM-27]

the biggest CPU draw for you right now is the fact that you are using 4K streams and then resizing them, this is less efficient than running detect on a certain resolution directly. You are also running detect at 10fps at 1920x1080 which will use a decent amount of CPU. Reducing to 5 or even 7 detect fps will lower CPU further.

That said nothing looks crazy high, your recording issues are most likely just caused by reolink camera bugs or some other issue and not by CPU usage

[mabed-fr]

I don't agree with you 100% I can correlate poor quality disk segments with CPU peaks. Don't forget that my machine only has two CPUs. Without forgetting that I have already optimized what I could which reduced the CPU load by two
