Testing the performance of a mobile Web application can be a challenge for many reasons, one of which is the difficulty in setting up a realistic test environment. End users of mobile e-commerce Web applications will access those applications, most likely, over 3G or 4G networks, meaning that any test done over Wi-Fi will not be accurate.

However, there are some commonly agreed upon techniques that can be employed to improve the performance of a mobile Web application. At the time of writing, the W3C provides a recommendation on Mobile Web Best Practices which is available from http://www.w3.org/TR/mwabp/.
