Help with optimizing my setup
Not sure if this kind of post is OK here, if not I've got no issue with it being taken down.
Hi everyone, I have my frigate set up with 3 different cameras with person detection on all 3 and some masks and zones set up. I've got a coral edge m.2 accelerator on the machine that hosts the frigate instance. I've just gotten it set up not too long ago and have been monitoring it's performance. A few times a minute usually, I get a warning saying one of the cameras is using higher than normal CPU (30%+). This wouldn't be an issue as it usually only lasts for a second or so, but any time this happens the feed that Home Assistant is receiving and displaying cuts out until it returns to under 30%, sort of defeating the purpose of having it tied into HA. I also notice that even though I have masks enabled, I still get a ton of recordings of things inside the mask zones.
Since I'm pretty new to frigate, I was hoping I could post my setup here and statistics and get some advice on how to improve. Overall, my setup is a Beelink s12 with the coral edge m.2 installed (I know it's out of support, I can't update it but it still works until I can find a replacement). Proxmox hosts Home Assistant and Frigate. Frigate has been allocated 3 CPU cores (of 4 total) and 6GB memory (of 16). Both of these stay pretty consistently under 30% usage.
My config is below. I got the settings offline from the forums or YouTube for setup, so I've got no idea if it's actually optimal. I mostly want to avoid things that may cause issues or the spikes in usage without knowing it. Any advice is welcome

What is the resolution of your cameras?
If it's high, you will want to use a lower resolution substream for detection.
https://docs.frigate.video/frigate/camera_setup/#choosing-a-detect-resolution
https://docs.frigate.video/configuration/cameras/#setting-up-camera-inputs
You'll also want to make sure hardware acceleration is working correctly.
