Chrome search page-rendering element begins from the top search results, where a user will likely click-on, its predictive-input, albeit not 100% accurate, definitely makes a top choice. The pages under the 'Instant Page' feature appears to load faster than without it, invariably meaning sacrificing accuracy for speed.
But, how much faster? Google had made available a video comparison of Chrome with and without the Instant Page feature on YouTube.
However, users that are worried about bandwidth cost can disable the feature by navigating to the tab settings/advanced and uncheck the 'predict network actions to improve page load performance' box.
Chrome's Omnibox, a combination of search box and address bar feature, is now even more smarter in the latest version. It now allows easier back and forth movement on pages visited.
The fact that Google is highly obsessed with speed remains visible in this search innovation. Also, following on the heels of its recently announced war against slow websites.
