Hight CPU usage during file transfer


Recommended Posts

Hi everyone, me again. So as a rookie to unraid, this is the last remaining problem for me.

First comes with the issue, the CPU usage went up very high whenever a file transfer starts. It doen't matter it's between docker to disk, docker to docker, vm to disk, vm to docker or computer through SMB. And I've tried wire and wireless connection. Average usage hits 30+% to 50+%, and single core usage usually goes to 100%.

 

Then something about my device.

1. i3-8100 with 16G ram

2. 2+3T hdd for storage and 128G sdd for cache with no parity disk. docker img and vm domins are on cache drive.

3. latest version of unraid.

4. Dockers: halo blog, aria2 with ariaNG, lychee photo, mySQL, mySQL admin, Jellyfin and nextCloud.

5. I haven't done anything yet for this problem, because I have totally no idea what is causing it.

 

And again, please let me know what snapshot and command I should run and provide to help solving this problem.

 

Thanks!!!
