CDN for mobile users: does it make any sense?

While CDNs have proved to be highly beneficial for regular Net, there is not so much information about its impact on 3G mobile network efficiency. A recent study performed by Web Performance Today team helped to clear it up.

First, keep-alive connections and HTTP compression were applied, which helped to solve the problem of TCP connections and reduce payload and resulted into faster rendering and 25% less file loading time. Then CDN was used, and the results appeared to be the following: doc complete time reduced by 1.4 sec (1%), render time reduced by 0.8 sec, time to first byte was cut by 39%, which slightly improves general performance.

The conclusion: CDN may be both helpful for desktop and mobile traffic, bringing positive impact on users’ experience, though, its efficiency differs.
