Pingdom report suggests images and scripting to blame
According to a report by Pingdom, web pages have grown at an astonishing rate over the past 12 months. The website monitoring company examined data from the HTTP Archive, looking at assets related to the top 1,000 sites in November this year and last. It found that over the past year the average size of a web page grew from 626 to 784kB.
"Web pages have been growing in size all along. The Web experience is constantly getting richer, getting more content, and people in general are getting increasingly capable Internet connections. It's a natural progression," concludes the report. "That doesn't mean we should stop caring about page size, though. It's still an important speed factor, and with today's freely available developer tools there are so many easy ways to analyze and optimize web pages that there really are no excuses for overly bloated websites."
