Hi there,

Im currently using QT 4.6.3 on a s3c2440 processor (Arm920T). I have serious speed problems while executing some demo apps.

As example i tried the Embedded Widget catalog.
The main speed problem is happening, when i move the mouse cursor on a Button, which changes color when the mouse cursor points there. It takes like 1-2 seconds until something happens again.
If i change the Page from Buttons to Sliders, it also takes about 2-3 seconds until the other Screen is shown.


My Setup:

- QT 4.6.3 ( im using 4.6.3 because of issues with 4.7 http://www.qtcentre.org/threads/36452-Arm9-amp-qt4.7 )

- s3c2440 on 400MHz Clock with 62 MB SDRAM and 62 MB Nand Flash

- i compiled QT static ( it improved the speed a lot, but still not enough )

- im using linux-arm-gcc Version 3.4.1 and compiled QT with optimization -o2


Am i missing something important? Or what could be the main problem of my speed issues?

Any help appreciated!
