[Qt-qml] which is faster ? Using javascript or qml only Statemachine through qtcreator's qml designer

[Pelle Johnsen]

Although I haven't tested your specific scenario, what I've found with
regards to QML performance on embedded devices for our project is, that it
takes time to instantiate the QML instance hierarchy. So if you have a
choice between creating a lot of QML Items (where maybe only a few are
visible at once), it may give you better performance using JavaScript to
handle the dynamics.
