In fact, Google Fellow Jeff Dean, in a keynote talk at WSDM 2009, slipped some words out of its chatty mouth which maybe were supposed to stay unsaid. She said that a single Google search query involves 1000 computers, while latency has gone down from around 1000ms to 200ms. She also said that Crawler updates now take minutes compared to months in 1999. Of course, if the time decreases, the  power and machines involved must increase. for sure. It is funny to notice how Google, in the past has stated to be the “greener” search engine in the world with just  0.0003KWh of energy for each search query. A rather unbelievable fact if compared to what Dean said just a few days ago!
