I am still puzzled by this, but I still have the open question about how much
memory the Go runtime really use. I am suspecting quite a lot, and the
ARM32 instance isn't on par with any contemporary server or desktop
when it comes to memory, it has ~2GB for a userspace program, after
that bad things will happen: the machine will start thrashing.

Do you have some idea about how much memory these Go binaries
use up at runtime on x86 or Aarch64?
