Topside

I may have celebrated a bit to early.

@Squidwas right (again) - at least for my case It helps a bit if i use my eyes and look at the right setting. CPU is doing just fine now

I have taken the good initiative of pinning the CPU for Sonarr, as this at least isn't taking all of my 8(16) cores Also I am using "cache"

Think I have something that looks the same. Two times I have confirmed that by shutting Sonarr docker down my CPU (all 8 cores) go from plus 90% to 0-20%. Both times, after i boot Sonarr the issue seems to be gone. I'll be more than happy to bring any info if it can help finding the issue

Have you tried adding a "pool" ?
