Unusably Slow Playback on Peertube??
-
Peertube playback is unusably sloooow for a 14mb HD test clip of 20 seconds.Current settings:
- 4gb of RAM on an 8gb vultr instance.
- Bumped up Redis and CPU resources as well just in case (no resources seem to be tight)
Also:
- I've deployed a Jellyfin instance with much less resources on the same cloudron with no problems with playback.
- Transcoding to other resolutions is off, so it's not busy transcoding the file in the background (stock .mp4 web video.)
- Nothing particularly interesting seems to be happening in the logs.
The download numbers in the overlay.....
I'm assuming Peertube at this point is a functional piece of software.....
-
Is it something to do with federation? My use case is to just have videos behind a login for a group of <50 people. Federation isn't really needed at the moment.
-
Any ideas as to what else I might try to make this usable?
-
Just to rule out the obvious - do other people face the issue when using your peertube ? Maybe it's not a server issue. If you send me us a mail to support@ with the domain, we can give you some test results if you like. Or you can always post the video link here on the forum, if that works.
-
@girish I've only uploaded one short test video on my PeerTube but that seems to play OK
-
@jdaviescoates thanks for this. I actually re-uploaded the same video to my instance to use it as a benchmark.
On your instance I can see the download speed spike to a more reasonable speed to get the video buffered as shown on the peertube interface:
This doesn't happen with mine.
So unless there was some sort of configuration that you improved (i haven't been able to find anything in the Peertube Admin), so at least thanks to your help we've ruled out that it's something to do with the basic function of Peertube. -
@girish I'll DM/email you. I'm out of ideas.
Only bottlenecks I can think of are:
- memory( i would think this would show up in the usage graphs)
- cpu
- disk i/o ( Vultr advertises SSD)
- network connection ( seems unlikely)
CPU seems the most likely culprit. Server has "4 vCPUs", CPU usage chart shows a spike from 18% to just under 30%:
Outside of my expertise here, but I believe by default Docker containers are single-threaded. On Cloudron I've got processor resource availability set to 100%, but perhaps it's possible this gets "under-reported" in the Vultr CPU usage chart because it's actually maxing out 1 of the 4 "vCPUs", but the PeerTube process is nonetheless maxed out......that's my current remaining feeble idea.I'll open a ticket with Vultr as well.

@tshirt-chihuahu how about you answer the question first? Upload a test clip --> make it public --> try to play it with a different device and/or from another network or link it here (if this is an option).
If your app crashes because of memory (OOM), Cloudron would notify you. If something is going wrong with your Peertube instance, the apps logs would show it. We try to think methodically and look for answers at the right spots other then guessing. Many times, the answer is blank obvious and most of the times just user error.
-
@subven Been working on it. Open to other hypotheses to better narrow in on the "right spots."
It's definitely not the device or the network—the clip kindly provided by @jdaviescoates downloads and plays just fine on same network/machine.
No sign of crash notifications. The app is responsive, the download speed of the video is just slow.
-
@tshirt-chihuahu is your Peertubes RTMP port allowed in Vultrs firewall?
-
@subven I have not explicitly opened that port on the Vultr server, so I'll assume not. However, I had been under the impression the RTMP was only relevant to livestreaming.....
I'll assume that's not the case now. Thanks for the lead.
-
@tshirt-chihuahu yeah you might be right. Just thought it could be relevant because Peertube uses a lot of federation and even torrent like downloading of videos. Normal browser playback should just work fine.
I did something nasty...installed a Peertube on the Cloudron demo server and uploaded a video
Download speed is around 51-61KB and it does not play play well at all (30 second 18mb file).Okay after some minutes passed I got 1mbit download speed with Chrome after a page refresh but this might be because of caching. You can check it out here until someone purges the instance ^^ I know this deployment is the worst case scenario but at least I have a fresh instance that somehow behaves the same like you described. -

Got it working on the Cloudron demo instance! Go into file manager and edit production.yaml. This is what I changed:
- line 123 --> accept_from: 'nobody'
- line 201 --> enabled: false
- line 238 --> enabled: falseline 130:
tracker: # If you disable the tracker, you disable the P2P aspect of PeerTube enabled: falseAfter disabling the tracker (and peertubes P2P function), download speed was instant and every video played just fine. If this works for you, this might be the solution! Ressource usage was standard - app memory at 512mb and redis at 150mb. No other changes made.

Hmm, interesting, I don't think I ever edited any config to turn any p2p or federation stuff off.
-
Thing is we don't generally touch upstream defaults - https://github.com/Chocobozzz/PeerTube/blob/develop/config/default.yaml#L282 and https://github.com/Chocobozzz/PeerTube/blob/develop/config/production.yaml.example#L280 .
I will put this in our docs.

Added a note in https://docs.cloudron.io/apps/peertube/#disable-p2p

Thats a fair position. Though, I have installed a fresh peertube on my private Cloudron server, gave it enough ressources and was able to reproduce the problem. Normal playback is not possible out of the box and the
P2PWebtorrent functionality seems to be the culpid. P2P works within your browser and my public (client/browser) IP is displayed correctlybut I still think it has something to do with the way Cloudrons setup works.Since I as a user assume that every app in the Cloudron store works without further configuration, I see a problem here. I wonder why this wasn't noticed earlier, since the
P2Pdefaults have been in peertube for over 3 1/2 years and the app is not new at Cloudron. To make my point: Just because it works upstream as a default, does not necessarily mean it works for us ^^ -

I wonder why I haven't hit this issue then? Pretty sure I've not done anything to turn P2P stuff off on https://video.uniteddiversity.coop
face palm on my part for not looking directly for a config file to turn off federation....
