[Minegamer95]

Please describe your bug

If i sync my movies using Syncthing to the storage of my Jellyfin Installation while Syncing is active i get a high CPU usage and Disk Read from my Jellyfin installation. When the Sync is finsished by Syncthing the CPU and Read Speed goes down to the normal.

Reproduction Steps

1. Add a Jellyfin Libary to Jellyfin
2. Add an Folder, which is getting Synct using Syncthing (Recive Only mode), to the Libary.
3. Add several movies to another device which sends the data to the Jellyfin folder via Syncthing4.
4. Now the CPU usage off Jellyfin goes realy high will Syncthing is Syncing the files, also it the File Read Speed goes high
