Everything is slow - Panzer19 - 2025-06-04

This is after installing on a NAS. In the past I've used Jellyfin just running off of Windows 11 laptop with an external HDD for my library and never had any issues. Really no issues. Since moving all my media and setting up a NAS, Jellyfin is very unresponsive and slow to load nearly everything. By that I mean images, libraries, and even playback. I can click something and it just sits there for a minute or two. This is the same on LG app, Firestick, Xbox, mobile, and PC apps. I find it hard to believe this NAS would not run JF as well as it would off an old gaming PC. 

I've ran a library scan several times. 

I really don't know what I can do at this point. Anything I can try? I does work, but it's so unresponsive. I'd rather not go back to having my PC on every time I want to enjoy my server. 

-Jellyfin Version: 10.10.7.r01
-NAS: Asustor Drivestor 2 Lite
-2.55 TB size library. 
-IronWolf 4TB HDD. 
-NAS is not used for anything else. 
-I deleted artworks and other files in my folders just in case that was bogging it down or something. 
-No plugins.

Not sure what your settings are. Could the server be generating "Trickplay" images? Deleting the artwork might also have had the opposite effect, in that it is gathering new metadata. I've always had a slow unresponsive server after a new installation. It takes a while for JFin to get up to speed when first installed.

Nah. No trickplay. 

It usually takes a while to get up to speed? What causes that? It has been a week.

I have no idea what to try at this point. I do not want to use Plex.

Is Jellyfin's DB on an SSD or a standard hard drive? I used to host Jellyfin on my NAS and it worked HORRIBLY when on a standard hard drive, and improved vastly when I migrated it to an N100 pc.

It's on the hard drive. Not sure of any other options I have as far as migrating it to something else. I tried to just put in on an external SSD. Not sure if that's even possible.

I'm no expert, so maybe someone else here has more insight, but the way I solved the same problem you're having was moving the Jellyfin app onto a system with an SSD, and only using the NAS for media storage. I know that's not a great answer to hear, so hopefully someone else has some better ideas for you.

You first need to find out if its a client or a server problem. Second thing then is to find out if it's a JF frontend or backend problem. This said:

1) Is it the same from different client computer with different client apps?
2) Is it only slow with media streaming or also to navigate the UI?
3) Is it only the GUI being slow or is it also the media scanning and so on?

4) Have you check server load on the server running JF? Also look for processes other than JF, i.e. ffmpeg.
5) Have you tried to turn off https and any proxies in front of JF and directly access JF?


General remark: N100 is a 4 core system with E-Cores only. It's great for general file serving, however when it comes to tasks where encoding and transcoding is needed, it will consume significant cpu power and as it's not very powerful in terms of media processing, it will take time. On top of this, JF is built on .Net and needs rather more than lesser ressources.

Btw, the Asustor Drivestor 2 Lite isn't what we would call a powerful machine.

Realtek RTD1619B 1.7GHz quad-core processor (core speed 1.1 GHz
1 GB DDR4 RAM
max read rate 110 MBits

However, it wouldn't explain the lag you are experiencing.
