Google Completes Caffeine Update 
By: Doug Caverly 2010-06-10 Google's new Web indexing system - called Caffeine - is ready to go, and the changes are significant enough that everyone from the most specialized SEO expert to an elderly person looking up knitting patterns may notice. Google promised "50 percent fresher results for web searches."
Curious how that's possible? A post on the Official Google Blog put the concept into somewhat relatable terms, starting out by stating, "Caffeine lets us index web pages on an enormous scale. In fact, every second Caffeine processes hundreds of thousands of pages in parallel." Then came the direct comparisons: "If this were a pile of paper it would grow three miles taller every second. Caffeine takes up nearly 100 million gigabytes of storage in one database and adds new information at a rate of hundreds of thousands of gigabytes per day. You would need 625,000 of the largest iPods to store that much information; if these were stacked end-to-end they would go for more than 40 miles." So while this doesn't represent a breakthrough in real-time search insofar as the subject relates to things like Twitter and Facebook, it's a meaningful move forward. Google explained that the Caffeine system should act as a base conducive to further advances, too. As for when those other improvements might occur, the blog post mentioned "months to come."
