Profiling QtQuick HMI Performance on Embedded Linux Demo of a QtQuick speedometer running on an i.MX6 board

QtQuick is a popular choice for creating HMIs for embedded devices. The hardware on these devices is often constrained and less performant than their desktop equivalents, this requires extra care from software developers in delivering a fluid user experience. KDAB is regularly involved in improving the performance of QtQuick HMIs on such devices for their customers.

In this demonstration, we will show how to profile and optimize the performance of a QtQuick speedometer, an example taken from an actual embedded project running on an i.MX6 board. We will demonstrate how to identify the performance bottleneck with the QML profiler in QtCreator,pointing out possible solutions and then choosing the best one.
