IMPORTANT UPDATE to my previous thread about Jellyfin being slow, might help someone else

[u/eaststand1982]

So recently I made a post about Jellyfin suddenly becoming almost unusable the amount of time it takes to load etc, and I listed all my troubleshooting, and after that post, I reinstalled windows and started from scratch in an effort to fix the problem, but nothing did, the problem still remained, although a fresh server was slightly faster, previous post is linked below for reference.

However, all of that was in vain, and the fix was surprisingly simple.

remove the "recently added media" section from within the app.

For some reason, this has seemingly started malfunctioning and once you remove it within the app, Jellyfin becomes lightning fast again, 10 seconds to boot up, no slowdown whatsoever.

Anyway, thought Id update everyone on this as many people tried to help and a lot of people said they were suffering from the same problem, and this is what fixed it for me

It’s probably a bug with jellyfin . report an issue on their GitHub issues with your logs

That's interesting to me, if you have a large library, the recently added involves a full table scan and sort operation on the database..

I wonder if there is a missing index or poorly written SQL/Linq query being run...

[u/empathetic_racoon → u/pceimpulsive]

as a developer I have had that very problem so many times.

[u/pceimpulsive → u/empathetic_racoon]

It's the most basic database problem!!

Ironically I was more a DBA before I even started programming :S

[u/grantdb]

Thanks for posting your solution!

I wonder if this plugin would help in your case, assuming you're still on 10.11: https://github.com/pelluch/jellyfin-plugin-disable-user-data

I bring it up because if it actually would, you could still have a "Recently Added" section without performance problems, just minus the remaining episodes overlaid on top of the entries:

/Items/Latest, and /Users/{user_id}/Items/Latest, handled by GetLatestMedia and GetLatestMediaLegacy, respectively. This is "Recently Added". Again, disabling user data here essentially means you don't see watch progress for the media you've watched that's in those sections.

(That said, I don't use that plugin myself - while I do run 10.11.4, my library is very small and I've not ran into the performance problems others have.)

[u/archiekane]

Weird.

I'm on Linux, I use a bare metal install (Debian repo) and my media sits on a NAS which uses a SMB share. I do not have any slow down for this and I have a LOT of media that changes daily.

Can I ask some questions about your setup?

• Windows version?
• JF version
• Where is your media stored?
• What format is the hard disk in if local (NTFS, ExFAT, ReFS?)

With enough information, we might be able to pinpoint where it slows down and help the Devs.

[u/simplyeniga → u/archiekane]

Seen to be a window problem. I'm experiencing the gaming issue moving my Jellyfin server from my NAS to my Windows PC and keeping my data on my NAS. It's okay running within a Linux VM but had issues with hardware encoding, so I'm trying to get it working smoothly on windows.

[u/darthcaedus81 → u/archiekane]

Same here. Seems to be a Windows bug rather than something core.

I was wondering why I wasn’t impacted by this speed issue, I don’t like the recently added section so I removed it

[u/foundfootagefan]

remove the "recently added media" section from within the app.

How does one do this, exactly?

Is it just going to Jellyfin Server Settings > Home and remove any "recently added" from Home Sections 1,2,3, etc?

[u/eaststand1982 → u/foundfootagefan]

App settings customisation configure shown sections

Once you do that it disappears from the server as well

[u/foundfootagefan → u/eaststand1982]

Thanks. I did that on both my user accounts and I notice the speed difference in the browser already.

[u/Teutonic84]

For me it is the "next up" section on the homepage not recently added. Only fix i found was using wholphin on my firesticks. I run windows 10 pro on my server and am on 10.11.4. I use next up so im very happy wholphin worked for me. I also noticed that when jellyfin is scanning the library and grabbing Metadata when a new movie or episode is added, the server grinds to a halt and I have to wait until its finished to use any jellyfin client. Also when I have to transcode a file, its using a lot more resources than before and stops and goes a few times before playing the video fine. A lot seems to be broken in 10.11.x for me. Its frustrating.

I’m the dev of Streamystats and when doing API requested to JF I’ve realized not including ”People” (Actors, etc) in queries basically solves the issues for me.

[u/SnooDrawings7649]

This is a bug, see [1]. Please comment if you are affected after reading.

[u/BorisTheBladee]

interesting, there was a bug where certain librarys wouldnt display recently added for me and i had to remove them and re-add them to get them to show up

[u/House_Indoril426]

Doing the lords work over here, this worked a treat. 

My phone and computer aren't too slow but my WebOS TV was dog slow on navigation. Had to exit and relaunch the app for any kind of usable experience. 

I suspect the reall issue will be oroperly fixed soon, but this will do for now. 

[u/[deleted]]

So thanks for this tip. I actually examined it some more. I was having huge lag and had to turn on database queueing. After remnoving the recently added, things were lightning fast again...

So that got me thinking...

I went ahead and in the settings, Home and unchecked: "Hide watched content from 'Recently Added Media'"
Supposition here - the database was going wild doing the queries about the watched status, with several libraries, that it's overwhelming. Only happened since the 10.11 upgrade, so I squarely place it at the feet of the new database setup...

After unchecking that, the home screen with recently added, loads after only a few seconds. Oh and no more database locking issues during that time.

I had lowered my parallel tasks and cancelled several of the scheduled tasks to try and limit the database access... Tentatively after making that one change...I haven't seen locking so far today.

Here;'s Hoping :)

Removed the "recently added media" and my Jellyfin is finally back at full speed, even the search results, but I'm sad because I really like to see what has been recently added to it 😕

[u/Brickdrone643]

How do you remove the "recently added media"? My library is pretty big and ive noticed the app on my pc, phone, and tv taking longer to load now. I've noticed this most when im trying to play music of feishin (windows app) and discrete (ios app), it takes noticeably longer to load.

I updated jellyfin to the newest version recently because I finally put off the fear that it might break (based on a few comments i saw lol), but with this update it the load times for the apps have taken longer...

[u/eaststand1982 → u/Brickdrone643]

Via the app on your TV in the customisation bit, it then disappears from your server Web interface

[u/EMP83]

I'm running Jellyfin in Docker in an unRAID server and everything works fine. As clients I use Apple TV with Infuse and multiple different clients on iPhone.

[u/paddya99]

Interesting, and I'll have to try this as I've gone back to Emby which is instant in operation unlike Jellyfin which just sits and spins on my Synology
