Mover maxing out CPU when moving large files

Featured Replies

  • Community Expert

here's the situation: in Sonarr, when a new download of an entire season has complete, the Mover gets moving from cache to the array, then my CPU all maxed out making the server unresponsive. Even the Main tab takes a long time to refresh and any other tabs also. And, if I'm watching a video on Emby, it completely stops. Trying to refresh Emby page makes it spin and spin...

Once the Mover ends moving, everything comes back to normal

To my knowledge, the Mover should mostly wait for disk IO and take little CPU

 

Everything is up to date

 

Any ideas whats taking all the server resources?

Mover is meant to be scheduled when nobody is using the server.

mine needs to run at every hours or on demand when im doing manual downloads

 

but, why the high CPU use?

In that case, you need to disable cache for those shares and download directly to the array, or set up a larger pool so that mover can be run during off hours.

 

The high CPU is to get the move done ASAP.

the Mover cannot move faster than the disks in the array. Even Windows does not use that much CPU to move/copy files, no matter the file size
