Chrome was built with speed as one of the primary missions since its start back in 2008 and now the coders have come up with the next thing to help make it even faster. Chrome is introducing two techniques called script streaming and code caching designed to reduce that painful waiting time spent staring at a white screen, especially on mobile devices.
Code caching is the second new technique that helps speed up page loading, specifically on repeated visits to the same page. Chrome 42 introduces an advanced technique of storing a local copy of the compiled code, so that when the user returns to the page the downloading, parsing, and compiling steps can all be skipped. This allows Chrome to avoid about 40% of compile time across all page loads.
Thanks to Chromium for providing us with this information
