MIT and Harvard University to develop tools to help load web page faster than the 34%

Polaris-a new engineering from Massachusetts Institute of technology (MIT) 's birth can help your browser collects the files more efficiently, thereby accelerating the web page loading speed.

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.

Download a web page is an extremely complex process. After visiting a URL or click a link, your browser will proceed to collect a series of object files, including HTML, JavaScript, images, and more.Each object is evaluated, then add to the web page you are viewing. However, the evaluation process that can lead to having to load something else, depending on the component dependencies (dependancies) of the object. The browser totally doesn't know what the right download additional content, until it get the first object. This makes the load a web page becomes more sluggish and that is also the reason for the birth of Polaris.

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. "

The research group has conducted tests of his system on 200 different sites, including ESPN, and Wikipedia. On average, Polaris has helped the web pages load more quickly than the standard browser of about 34%. Written in JavaScript language, Polaris can be used for any web page and its performance does not depend on the browser. But the long-term hope of the scientists is to integrate it into the browser that we use. In the next few months, the research team intends to disseminate their stuff for everyone, in order to receive ce the feedback, from which improve the effectiveness of the Polaris.
