Nextcloud Talk CHAT very slow

[i.fritz]

Hello!
We have the problem that Cloudron Nextcloud Talk Chats are very slowly. Entered text is shown 20s-30s later. We use HPF-backend for video, this works well.
I searched Google for that and they say it's a problem with http2 and Apache mpm_prefork. We had to use Apache mpm_event instead (or maybe disable http2). Is there a way to change Apache mode to mpm_event? I just see a Apache config for mpm_prefork where I highered values to this Nextcloud (> 100 user).

I don't think it makes sense to do changes on command line if next docker version overwrites all setttings.

Bye,
Ingo

Do you have this link? What could be the problem with http2 and mpm_prefork be? http2 is everywhere by now .

http2: "After disabling http2, messaging is possible nearly in real time"

nickvergessen2 (Nextcloud Talk developer at Nextcloud GmbH) 08.05.2025:
"It's a misconfiguration on your side, nothing we can fix software side. If you run PHP FPM you need to run the Apache "event" module. FPM + "prefork" will never work"

FPM + Apache prefork is exactly, what Cloudron Nextcloud is working. So should be changed to mpm_event.

I will take a look at it.

Hello @i.fritz

Could you go into a little more detail here?
A: You write some text, send it and have to wait 20s -> 30s until the message appears in your local chat
B: You write some text, send it, the receiver gets the message 20s -> 30s seconds late

I could not reliably reproduce this. Also, I don't have access to >100 User Nextcloud for testing more close yto your setup.

Maybe a small video of the problem could help to understand it.
If you make one, please have the browser console open so the console logs are viewable.
