Analyzing and Solving Qt UI Performance on Embedded Hardware

This demo was recorded at the Qt Developer Days in Berlin in 2013. When developing UIs for embedded devices, it is not uncommon to hit performance problems on target hardware -- whether the UI start-up takes too long, animation is slow, or the UI isn't responsive enough. The source of many embedded UI performance problems are system level problems coming from outside the UI layer. This presentation will provide practical help to developers on how to solve these common UI problems on target embedded hardware, looking at and demonstrating tools and techniques to analyse the problem (ranging from the humble printf, to more sophisticated trace tools). This guidance will be backed-up by examples of how the author has used these techniques to solve real-world Qt UI problems.
