QML performance analyser
Nokia's Qt Labs have posted a walkthrough on their latest tool: a Qt Quick profiler and performance analyser: As QtCreator 2.2 is coming out, we have started working on new experimental features in a new branch. The latest of them is the Qml Perfomance Monitor. This little tool, part of the new Analyze Mode, can be used to profile your Qt Quick applications. With it you can inspect binding evaluations, signal handling, and painting operations when running your Qml code. This is very useful for identifying potential bottlenecks, specially in the evaluation of bindings.
