The speed of the Internet are becoming faster, but the site has too much complicated, and that is why we often have to wait to download the complete contents. "When the site increasing complexity, they often require many elements that make up the delay", Ravi Netravali-one of the researchers explained. "Our approach will minimize the number of round, which can increase the page loading speed up dramatically". Polaris has been developed by scientists from the University of computer science and Artificial Intelligence Laboratory (MIT) and Harvard University.
The black line expresses the typical order of objects on a web page is loaded, from top to bottom. The red line demonstrates how Polaris connect the dots together.
The Mission of the Polaris is recorded all the dependancies and "burying" them away. It will sum up all the dependencies and create a chart, helping the browser to download the components of the site more efficient. To easy to understand, the researchers compared it to taking someone's travel. "When you visit a city, sometimes you can discover more of the city you want to visit, before going home. If someone gave you the entire list of cities before, you can plan for the route as quickly as possible.However, if you do not have this list, you will have to go round the middle of the city ... for browsing the web, downloading all the objects of a page like going through all the cities. Polaris effect in that it gives you a list of all the cities, before the trip really began. "
