If frames get dropped even though JavaScript is not being run, and there are large, unexplained gaps in the timeline, check your customQQuickItemimplementations. You can useValgrindor other general purpose profilers to analyze C++ code.
In this chapter, we will see how to perform the runtime profiling of QML applications using the QML performance analyzer and learn how to read the reports it generates. We will then turn our attention to memory performance analysis with Valgrind ... ...
