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.
They don’t care, that line in the ToS was removed years ago now.
I believe it was moved, not removed, and that it is now located in a different document, but still applies.
No it was definitely removed, they now have essentially “don’t be an ass with the bandwidth.”
No, it was moved. It now sits in their CDN service terms; the difficulty is in determining whether tunneled traffic constitutes CDN usage because CF are kinda vague on this stuff. Are they going to limit your account over a little streaming? Probably not, but I would not risk it unless you don't really care about the account.
Tunnels aren’t inherently CDN, you can tunnel UDP info for instance (if you use cloudflared on both sides) and inherently transient things such as websockets.
I’ve had none of my media be cached in their CDN for instance. In fact you’d likely have to do some hoop jumping to make it happen.
