The Chrome team is working on a back/forward cache that is designed to make revisiting pages drastically faster. By preserving the JavaScript and DOM state in memory, loading times of cached pages will be significantly improved.
On desktop platforms, nearly 10 percent of all pages loaded are from the forward and back buttons. Mobile use bumps this stat up to 19 percent of page loads. If Google can pull off this feature well, browsing will appear to be far more responsive and seamless than ever before.
