Google’s mobile search has got faster – to be exact, 100-150 milliseconds faster.

According to a Google+ post by the Google Chrome Developers, when you click on one of the search results, the browser begins fetching the destination page… & here’s the trick: Google also provides a hint to the browser indicating which other critical resources it should fetch in parallel to speed up rendering of the destination page.

According to Google, this is a powerful pattern & one that searchers can use to accelerate their Sites as well.

“The key insight is that we are not speculatively prefetching resources and do not incur unnecessary downloads. Instead, we wait for the user to click the link and tell us exactly where they are headed, and once we know that, we tell the browser which other resources it should fetch in parallel – aka, reactive prefetch”, according to Ilya Grigorik of Google.

For now though, this feature is enabled only for users of Google Chrome on Android, as it is the only browser that supports dynamically inserted prefetch hints & allows prefetch requests to persist across navigations.
