Here's an interesting statistic: Based on 148357 servers consuming 72500 kW of power, Microsoft's average server is using 488 W of power at any point -- so clearly Microsoft is not following Google's approach of using smaller servers which each draw 200W or less. Is the Windows kernel better at using large boxes than the linux kernel? Is Microsoft worse at managing clusters than Google? I'm sure there's some reason w…
