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?
