Responsive Web: The Importance of Client-Side Performance

/, Responsive Web Design/Responsive Web: The Importance of Client-Side Performance

One of the goals of developing a responsive website (RWD) is to assure a flawless user experience across all digital platforms (web, mobile, IoT). To achieve that goal, there are functional testing considerations that should be taken into account such as proper test coverage goals, navigation testing and visual testing. However, one of the most important test considerations for RWD from a UX standpoint is the client-side performance of your responsive website.

Users these days are often transitioning between digital platforms such as desktops, tablets and smartphones and they expect to get the same experience, responsiveness and performance at all times. The challenge is these devices have unique characteristics such as screen sizes and resolutions, which can affect a website’s performance against real network conditions. Unfortunately, the result can be slow load times and laggy performance. To manage these challenges, RWD developers need to do all they can to optimize the site code and content so the site matches the device screen it’s running on.

With sites containing 400+ different objects per page, any mismatch of an image to the device screen size and resolution will add time to the page load on that device. This adds up to a significant delay on mobile devices, which are already under a heavy load with background-running apps, battery stretch and network activities. With so many existing barriers to a smooth user experience, poor responsive web design will only make matters worse.
