Best Way to Optimize a Qt Quick Application for Smooth Performance?

[michaelcarlos]

Hi Qt Community,

I was working on a Qt Quick app and Google Cloud Console found that it has some performance issues, particularly in managing animations and complicated UI elements. It is working perfectly on high-end hardware but gets slowed down on low-end devices.
I'm utilizing Qt 6 with QML and applied some of the optimizations such as decreasing bindings, caching through Layer.enabled, and capping JavaScript logic in QML files. Nevertheless, I'm still encountering frame drops in transitions.

Some highlights of my application:

lots of ListView & Repeater usage
ShaderEffects for custom UI
Dynamic loading of components
What are the most effective ways to optimize performance further? Are there any profiling tools that are Qt-specific and will allow me to identify bottlenecks?

Would greatly appreciate any advice from those who have optimized Qt Quick applications in the past!

Thanks in advance!
Regards
michaelcarlos

The QML profiler built into Creator (Analyze -> QML Profiler) has worked for me in the past.
