Especially for x86 cross compiling from ARM. Typically people do the reverse, because outside of Graviton and M-series, X86 is generally a lot faster.

Yeah, I remember compiling for Pi with QEMU on my amd64 was infinite times faster than compiling on Pi itself. I think people don't understand a few things:

- running self-hosted services for 3.5 users doesn't take many resources and Pi can often handle multiple services

- Compilation is CPU heavy and I/O heavy operation, more memory you have on a single machine is better.

I use Pi as my on-the-go computer in places where I can't ssh to my home-server. Sometimes I can't even get projects indexed without language server being killed by OOM 20 minutes later (on my PC it takes <20 seconds to index).
