MIT’s sharp trick to loading of webpages – Coder In Me

Computer scientists of World-famous Massachusetts Institute of Technology (MIT) have revealed a system that can reliably make webpages load 34 percent faster. That is MIT’s sharp trick to loading of webpages.

 

Day by day internet speeds have increased, webpages have got more complex, leaving some pages sluggish and unresponsive. This is a problem for companies like Amazon, who say that for every one-second delay in loading time, their profits are cut by one percent.

 

But a team of intelligent researchers, working at the University Computer Science and Artifical Intelligence Laboratory, may have found the solution.

The system reduces load-times by determining the best way to ‘overlap’ the downloading of different parts of a webpage and named ‘Polaris’.

Here’s theĀ  MIT’s sharp trick to loading of webpages –

Whenever you visit a new webpage, your browser reaches across the internet to fetch ‘objects’ like pictures, videos, and HTML files etc. The browser then evaluates the objects and puts them on the webpage.

 

Anyhow, some objects are dependent on others, and browsers can’t see all of these dependencies until they come across them.

 

Polaris works by following all of these relationships and dependencies between objects on the webpage and turning the information into a ‘dependency graph’ that can be interpreted by the browser.

 

Polaris essentially gives the browser a roadmap of the webpage, with all the details of the best and fastest way to load it.

 

Ph.D. student Ravi Netravali, who worked on Polaris, explained it”It can take up to 100 milliseconds each time a browser has to cross a mobile network to fetch a piece of data.”

 

“As webpages increase in complexity, they often require multiple trips that create delays that really add up. Our approach minimizes the number of round trips so that we can substantially speed up a page’s load-time.”

 

The researchers tested Polaris across a range of network conditions on some of the world’s most popular websites and found it made them load an average of 34 percent faster when compared to a normal browser.

 

Polaris could be used on any website and with unchanged browsers, and when tech companies like Google and Amazon are working hard to improve load-times
