Slow library scans on Synology DS923+

[skribe]

Standard ones + Merge Plugin.

I am scanning a cloud service, documentation says that currently image extraction cannot be disabled (even unticked) and that can cause performance issues. Seems like that. Just gave Emby a try and all is running flawlessly.

Seems known since Jan 2020 according to Github so i dont think this will be fixed in a short time.

I use Jellyfin with cloud storage myself without issue, so I don't suspect that's actually the root cause here. You're welcome to share logs and we can see if there is any information there. It doesn't even really sound like you're experiencing the same issue as the OP in this thread.
