Are you sure you are at least running the release version of your application?
Debug version uses the debug CRT libs (and a debug Qt which does the same), so everything will be a lot slower than the end product. You cannot really evaluate performance with debug builds. -- Sent from my Nokia N9 On 1/13/12 23:12 ext todd.r...@nokia.com wrote: Just for fun I’ve been playing with a medium-sized QML app that we had written for 4.7/Symbian and porting it to Qt5/QML2. Mostly have been working on Linux but the past few days I finally got around to compiling Qt5 on Windows and playing around with the project enough so that it would compile and run under qmlscene (it’s mostly qml/js with a C++ plugin module as well). Anyway, the performance on my Windows box is horrible. ListView scrolling, image loading, animations, everything is like it’s running in quicksand. Is this expected? If not, what do I need to do to in order to troubleshoot? This machine is relatively old and has a crappy video card (older Nvidia Quadro), but it should be more than good enough to run this app smoothly. Any tips or tricks to enable extra debug tracing?
