Hope the Moodle experience on Ubuntu 19.10,rPi4-4, will encourage the emergence of a 'rPi4-4 MoodleBox'
FYI, MoodleBox already works on RPi4: https://moodlebox.net/en/news/version-3.0.0/.

Re: number of users that can connect to raspberry 3b

Even without knowing how to write a program, I think quite a bit about the problem could be understood from reading the comments in the driver code and would encourage you to try and do so. Yes, you're probably right. Would you mind give me a hint where to start? (Where in the source code should I ...

Have you tried reading the comments in the Linux driver source code to see whether any configurable limits exist and whether the hardware has other limits?
I'm afraid not, since I can't code Linux driver :-/. But Jamesh has doubt that the problem is a limit in the code.

What happens if you swap out the Pi 3 for a 4B with 4GB memory?
Unfortunately, it doesn't change anything :-(. To summary, same issue on RPi 3B, 3B+ and 4B.

That the sort of information I was wondering about. There could be some sort of limit in the wireless SW somewhere, but I have not seen anything.

Re: number of users that can connect to raspberry 3b

I completely understand your use case. You just aren't grasping what I've said. The bottleneck may or may not be in a service on the Raspberry Pi. If it's hostapd (which equally has a RAM requirement for each connected user) which creates a bottleneck then fix that with an external access point. [C...

Re: number of users that can connect to raspberry 3b

Wonder if a different WiFi dongle would help? Rather than the internal one try a USB connected one. I know it defeats the ‘one box’ idea but does the same thing happen if you use an external AP and connect back to the Pi via Ethernet? I'm sure that this would do the job, but as you say it'll defeat...

Re: number of users that can connect to raspberry 3b

Are you saying that each new wifi connection take so much RAM that after 25 users the RPi freezes? Interesting (I thought myself it could be a wifi driver problem.) I'll try to do some tests to see wether your assertion holds. No, I'm saying you need to measure the base RAM usage when the system is...

Re: number of users that can connect to raspberry 3b

Interesting, what do you think is the cause of the limitation? It's 100% guaranteed to be lack of RAM. Each user will take a chunk of RAM on the server. When that pushes your server over the 1GB limit (into swapping hell) you'll reach a practical limit. The big iron I work on for my day job runs ou...
