CPU Pegged at 100% - I can't figure out why

I'm trying to figure out why my system is pegging cpu 0. Do I need a faster processor? Is there something I need to do to get this to thread better?

 

I'm running

Ryzen 9 3900x

128 GB of DDR4 2133MHz RAM

 

I can't figure out why I'm pegging my CPU 0 all the time.

No one?

Server load is quite high, and there's something reading and writing to at least two disks in the array, so it might be normalnormal, but you can stop everything if you want to find out what it is.

Sonarr has quite a large database. I can't figure out why it's only using CPU 0.

 

is unraid that single threaded?

I believe shfs is single threaded for a single operation.

I have quite a bit going on. 

My App volume is two NVMe drives in a RAID 0, thats the drive thats so busy.

 

I set aside CPU 0 for unraid, but it's not enough apparently. I would like to see SHFS become multi threaded. Even if it's just kept to the first 4 cores or it's assignable with a required minimum.

 

I have 24 threads, but I use CPU 0 at 100% and the rest run about 1-5% most of the time. I see this as an issue, I have a pretty robust processor even with it being a few years old. 

 

Would I benefit from a 5950X? or should I wait to upgrade to a server grade processor?

@limetech is there anyway to improve performance?
