If you're measuring in terms of time, electricity, or hardware, then the threshold would tend to be lower for Google, not higher. A 0.1% savings on a million machines is ~1 million times more valuable than a 0.1% savings on a single machine. OTOH if the measurement is risk of breaking something, then it's not nearly so clear, since larger organizations tend to have more software and hardware, and therefore more opportunities for things to get broken.
