What is the best RPI OS for AIS catchers?

[luckbert]

Hello everyone,
I am currently building an AIS receiver.
The basis could be an RPI3b+ or an RPI 4.
I currently have the problem that the current OS for RPI 3 is very slow. Maybe it's the USB stick, who knows.

The question is whether it's worth finding out. Are there any significant advantages to using an RPI4?

Which OS do you use on the RPI3? 32 bit or 64 bit? Buster, bullseye or bookworm

Hello,
My feedback.
pi 4 used: Raspberry Pi 4 Model B Rev 1.4
cpu load is very low.
OS: Debian GNU/Linux 12 (bookworm) aarch64
Memory: 2Go installed
Why pi4? because I have one.

Hi, why do you say that the 3B+ is slow? I think that as a standalone AIS-receiver it is perfectly fine. I am using Raspbian btw and it is a bit slow to build the program but once it is up and running it can manage the processor load (think about 30% CPU load). You cannot do a lot of other things with it at the same time.

Pi4 is much more responsive, and on a Pi5, processor load is even less than 2.5%. So, both give more headroom to do other things with it in parallel.

So depends very much. I think Raspbian is a good choice if you are new to Raspberries, simply because there is a lot of support.

Thanks for the info,
That's exactly what I wanted to know.

Probably my memory (USB stick) is not a good choice.

I'll try again with a new SD card.
