has long been telling us how long it took to perform whatever search we sent its way. That little note may seem self-congratulatory to the average Internet user, but it’s vitally important.

Slowing that number by just 4/10ths of a second, for example, would cut 8 million searches from Google’s daily total of 3 billion.

If its pages took one second longer to load, Amazon , for example, could lose as much as $1.6 billion in annual revenue. These and other findings are included in a smart new infographic from OnlineGraduatePrograms that sheds light on the need for speed when it comes to Web page .

All of this emphasis on instant gratification comes at a time when the Internet is trending towards being more visual , meaning Web designers need to find ways to create image-heavy sites that still load quickly.

The chart also shows we remain impatient once we click through that top result Google gave us: half of us will abandon a Web page that takes more than four seconds to load.

The stakes are getting even higher as more traffic moves to mobile devices: 40% of shoppers accessing an e-commerce site with their smartphone give up after just three seconds of waiting for a page to load.
