gollark: Random hardware initialization and detection, probably busy loops to spite you, sort of thing.
gollark: Due to different design constraints, fewer peripherals, and less overhead I guess.
gollark: Yes, exactly, they're typically much much faster.
gollark: Perhaps "serious" computer systems on hardware when they were made never booted that quickly, but special-purpose devices easily take less than 5 seconds for bootup.
gollark: Don't?
