"Feel the Need for Speed? One of the key improvements in Google Chrome is the way the browser manages your computer's memory. Tabbed browsing, where you open a new Web page in a tab in the same browser window rather than a new window, is a common feature in all the major Web browsers. It makes it easy to surf several sites at once, but it can also be a drain on your computer's memory. Most browsers treat those different tabs as a single operation within a single browser window. In other words, if you have five tabs open, it's like sending five requests to your computer's memory. If one of the tabs slows down, the entire browser slows down. Google Chrome solves this problem by treating each tab as a separate operation. When you open a new tab, you're opening a new area of computer memory dedicated to that tab. If something slows it down, your other tabs will still run normally. If something in that tab crashes Google Chrome, you can close that tab without closing the browser. " Source - Life123.com
