Add a heatsink and fan. You'll get better performance.
Just run current firmware from last september or later and keep the pi4 standing up on its side naked, it will never throttle no matter what you throw at it. (unless maybe your room is 80F or more) I've had my pi4 compile stuff for days on end and it does not throttle if the above setup is followed.
I think the main issue keeping the pi with a 32b userspace is the lack of availability of 64bit GPU firmware
> I think the main issue keeping the pi with a 32b userspace is the lack of availability of 64bit GPU firmware Uh, no. It's there because of the design goals and priorities of the Foundation. They want to be able to distribute a distribution that runs on any raspberry pi generation. Performance is of secondary concern to them. So Raspbian remains at 32-bit.
Has anyone gotten the aarch64 Raspberry Pi image of Alpine to work on the Pi 4? It seems like a good fit for a RAM constrained system but I could never get it past the colorful boot screen.
One of the things that I find great about Raspbian is that the boot files are stored on a FAT32 partition which is readable from any OS, and there are some nice considerations for headless setups: drop in a wpa_supplicant.conf to configure Wi-Fi, `touch ssh` to get OpenSSH enabled at next boot. Do any of the alternative OSes, like Ubuntu, offer this?
ARM or X86 I really don't care...
Slightly off topic, but kind of on theme at least: does anyone know where to get an SBC (single board computer) with 6GB of RAM... or even 4.5GB (that doesn't cost like $~300)? The raspberry PI is almost perfect, I just need slightly more ram per unit. ARM or X86 I really don't care...

There are a few more. You could also build your own. All you need is a micro ITX motherboard + ram and a processor and something to power. Get them used and it will be way more powerful.

What did the firmware change to enable this kind of performance?

Yes. All 9 of my rpi4 systems run the aarch64 image. I some issues with 3.11.0 but 3.11.3 should work pretty well now.

I have not used or had a need for hardware GL. Don't even know what MIPI is. I use it as very cheap bare metal. Still plan to use 3 of them as Ceph monitors.
Sounds like you're using them as servers. Doesn't the lack of ECC worry you?
Ceph monitors aren't in the data path and Paxos is robust against byzantine failure, so...

Can you cite a source for this claim?
