I’d like to see a calculation on the global cost for wasted bandwidth. What is this going to cost in terms of CPU cycles, cooling, power, etc?
If 1 out of 5 searches is predicted incorrectly, the cost is going to be gigantic. Or is it? Google has 1 billion searches a day. 6 billion preloads not used per month. 320kb/page (a Google number). 1,920TB of bandwidth wasted per month (someone check my math on this). Not so huge. This assumes a preload of a single page per query. Still, not so green and certainly bad for the planet. Does Google own any dark fiber? Any extension of the preloading would be a slick way to chew up lots of existing bandwidth.
