[Feature] How long should a scan take?

[jgeorge1983]

I have around 7.5k episodes on my NAS and after 16 hours scanning I was at 20%. I'm running a rasberry pi4, and run Jellyfin in docker.

I dont mind leaving it running, but I also have HomeAssistant in docker and find that when I run the Alayze Episodes, it seems to interfere with my HomeAssistant instance, I think just a resource issue.

So just wondering if there are any benchmarks for how long I should expect it to run?

Server: raspberrypi Version: 10.8.0 Operating System: Linux Architecture: Arm

I found raspberry pi4 not good enough for Jellyfin. My last scan took 10 hours.

[jgeorge1983]

I'm slowly thinking the same, thanks for the update

[sourpatched]

10 hours on Intel Core I so your scan may take days.

[jgeorge1983]

Could take a week!

[Pfuenzle]

My scan took about 2 full days on a beefy machine, so theres no limit

For me it took about 2 hours for 9k episodes with my setup:

• OMV 6.0.29-1 (Shaitan) (on SSD) - Linux 5.16.0-0.bpo.4-amd64
• AsRock B550M-ITX/ac
• AMD Ryzen 3 3100 4-Core Processor
• 32 GB DDR4
• 2x18TB Western Digital Ultrastar DC HC550 (Stripe)
• 1x 4TB Toshiba HDWE140, 1x 3TB Toshiba HDWE130
• 1x 240GB ​Intenso High Performance SSD 240GB (M.2) )(for configs and metadata)
• Nvidia Quadro P2000
• Jellyfin 10.8.0 (Official Docker image)

@jgeorge1983 @conkydong How are you finding out how many episodes?

[jgeorge1983]

I have another app, medusa, that handles all my downloading, and that has a running total.

Other than that, right click >>> properties, would give you total of files, that would be a rough guess but may include subtitles, images and other files.

@sourpatched I ran the following in a terminal on my server:

ls -LR /folder_to_my_tv_shows | egrep '\.mp4$|\.mkv$|\.avi$' | wc -l

[sourpatched]

@jgeorge1983 I have meta data stored with the shows so that won't work.

@conkydong Thanks, I'll give that a try when I access the server.

"Switch to single precision fftw, enable neon for arm" in jellyin-ffmpeg 5.0.1-7.

This should help the performance on Arm platforms.

Awesome, thanks!

[nyanmisaka]

Are you running 32bit or 64bit Pi OS?

[jgeorge1983]

I presume 64bit, as its a Pi 4b

Linux version 5.10.103-v7l+ (dom@buildbot) (arm-linux-gnueabihf-gcc-8 (Ubuntu/Linaro 8.4.0-3ubuntu1) 8.4.0, GNU ld (GNU Binutils for Ubuntu) 2.34) #1529 SMP Tue Mar 8 12:24:00 GMT 2022

[nyanmisaka]

v7l, arm-linux-gnueabihf-gcc-8

Nope. It's armv7 armhf 32bit. You can switch to 64bit Pi OS for better performance.

[jgeorge1983]

do you know of an easy way to switch or is it a rebuild?

[nyanmisaka]

You have to reinstall it if you want, the dependencies are totally different.

[jgeorge1983]

looks like thats a few hours of my weekend sorted, the wife will be pleased ha :)

[JamsRepos]

It took me around 2 weeks for 150,000 episodes, this was using an iGPU which was the 7700. This wasn't constant however, as sometimes the scan would fail and it would require me to restart it.

[NightHammer1000]

About 3 weeks on an Intel Xeon E-2186G with around 50TB in Episodes from an rclone mount.
