I’ve been trying to upgrade from 10.10 to 10.11 for a while now, as the Android TV app keeps nagging me, and every attempt ended with impossibly long library scan times.
After some thorough investigation, it appeared that a Home Videos type collection causes unending scan (yet to be solved), but also that Jellyfin does a lot of writes to the config directory (either database or metadata or both). Mine’s on spinning media part of a ZFS pool. I tried a few performance tuning options, such as testing the config dir with recordsize (similar to block size) of 4K, 8K, 64K, 128K and library scans fell from 30-40 minutes down to 8-13min with 4K-64K. The ZFS tuning wiki suggest 64K recordsize with LZ4 compression for SQLite workloads such as Jellyfin. That seems to work as well as 4K and 8K but likely is faster when reading thumbnails and such.
Note that upgrading to 12-rc3, which is supposed to speed up library scans did not improve scan times for me. Optimizing config/database write speed did. I cross-checked the culprit by experimenting with moving the config dir to NVMe and RAM. Both of those got the scan times down to 8-9 minutes compared to the optimized spinning media’s 12-13.
So if you had upgraded (or about to) to 10.11 your library scans are (about to get) dog slow and your Jellyfin’s config dir resides on spinning media, optimize its write performance for SQLite.
I’ve always kept my apps and databases on solid state media, putting them on spinning rust, even in a well tuned ZFS pool with lots of disks is way too slow for their (admittedly inefficient) database.
This is true but it’s nice to have the whole app, data and database in one place, going together, snapshotted together, “backupable” together. It’s slower for sure. That said it can be reasonably fast with a large pool (more disks). With the magic of SSD cache, database reads fly and reads are the majority of the loads in my heads. In the future I would put root on ZFS as well and either do SSD cache or have root on ZFS SSD pool that gets send/recved regularly onto the spinning pool so it’s easy to restore when needed.
Isn’t it ironic that you post this meme along with complex instructions to fixing a problem in jellyfin?
With great power come great … uuh … :D
Also the meme is just bait so you read abt the problem and see if you need to solve it for your setup.
Excellent bait
Also doesn’t jellyfin not support remote streaming?
It absolutely does but you have to do it yourself, they dont accept any liability for doing that and nor should they, so if you dont know how to do it with at least the minimal level of safety and security and accept that risk yourself then you really shouldn’t try. Ideally you would only do it via a private VPN to trusted users.
Plex has some features built in to make just opening the port reasonably safe, though I’d still recommend against that. They also have a reasonably secure account verification system, and the software itself has proven to be somewhat safe.
Jellyfin has very little security built in and is not intended to be public facing, it also has the double edged sword of being open source, so you could read through all the code and pick it apart for flaws and exploits if you wanted to and we all just trust that when exploits or flaws are found they are reported properly.
JF is great but you are on your own if you want to make it available via WAN.
It’s a nonsensical statement. Jellyfin is accessed through a website. You’re responsible for routing to it.
If you use folders a lot, the library will get faster with v12 https://github.com/jellyfin/jellyfin/issues/15141
OP said this didn’t improve their situation though.
Doesn’t jellyfin need a static IP.
