by James D Bloom

Published May 27, 2012 in Programming

The key to a successful mobile site is high performance and reliability across a wide range of device capabilities and network latencies. However, the mobile web is a hostile environment with support for HTML5, JavaScript and CSS varying widely across browsers and devices. This talk will explain best practices to build high performance mobile sites that work across a wide range of devices and capabilities. The focus will be on lessons learnt at Betfair while rewriting the entire mobile web stack and how we used techniques to maximise performance and reliability. After discussing the problems faced in mobile the talk will explain how adaptive techniques can be used to provide progressive enhancement. This will be followed by an explanation of why and where performance bottlenecks occur and how these can be solved.
