GoogleÂ’s Jeff Dean At WSDM 2009
Google Fellow Jeff Dean, while delivering a keynote speech at the 2009 Web Search and Data Mining (WSDM) conference, gave some specific details on how Google has grown in the last ten years. Given how rare it is for Google to talk about actual specs like this, I thought it was pretty interesting.

Jeff gave several examples of how Google has grown from 1999 to 2009. They have x1000 the number of queries now. They have x1000 the processing power (# machines * speed of the machines). They went from query latency normally under 1000ms to normally under 200ms. And, they dropped the update latency by a factor of x10000, going from months to detect a changed web page and update their search results to just minutes. |
