The Responsive Paradox

Paradoxically, this weight increase happens despite the fact, that most modern web sites are designed responsively, meaning that they are specifically designed to also run on mobile devices. Smart phones and tablets which swallow expensive data via occasionally poor mobile connections.

Part of this weight increase is even due to the responsive web design itself, since more code is needed to make a web site work across different devices. The largest part of the overweight, though, is due to images, which have increased with 172 kilobytes or 21.7% during the same period.

The lack of an effective method to serve different image files to mobile and desktop respectively is gradually becoming clearer. Thus, 72% of responsive web sites are sending the same amount of data to both mobile and desktop.

There is a massive need for focusing on performance.
