Description of issue:
Hi Guys,
I’m currently running Sonarr along with NZBGet on a Synology NAS - both are running in Docker (linuxserver.io’s images). Episodes are initially downloaded to the NAS, and are then transfered to another HDD attatched to an Nvidia Shield for permanent storage. The Shield’s HDD is mounted to the NAS using CIFS.
When copying files from the NAS to the Shield’s HDD, using the mv or cp commands in Docker or copying manually, transfer speeds are around 60-80 MB/s. However, when files are being moved by Sonarr transfer speeds max at around 10-12 MB/s.
Any ideas why this could be happening? I’ve read that Mono has some problems with CIFS mounts (specifically truncation of large files?) - but I’m not sure if that’s applicable here as the CIFS share is abstratced behind Docker.
I would try NFS mounts, etc, but unfortunately the Shield only offers SMB/CIFS sharing and I’m not overly enthusiastic about rooting it.
Any help is much appreciated - thank you!
(I know this is similar to this thread: Sonarr move file speeds slow but it received no replies)
