help with QtWebkit performances

Hello all,

I succesfully configured and build Qt 4.6.2 for WinCE using this configue
options line:
configure -fast -platform win32-msvc2008 -xplatform
wincewm60professional-msvc2008 -webkit
setcepaths.exe wincewm60professional-msvc2008...nmake

Then, I have developped a very simple application that uses a QWebkit item
to display this page: http://www.hesido.com/web.php?page=javascriptanimation
I deployed my application on my device, a Touch HD Pro
with Windows Mobile 6.5... and horribles news, I found that animations with
javascripts,
like moving the little button in the page, are little slow.

I though that it could be a problem of the parameters in the qt
configuration, I searched if
there is another way to reconfigure and build qtwebkit with another
options, but it does not exist. I'm missing something???*

I think that I will try to download the last version of
Webkit at
"http://svn.webkit.org/repository/webkit/trunk" and try
to recompiles QT with the instructions here:
http://trac.webkit.org/wiki/BuildingQtOnWindows.
However I don't know if that instructions are the
corrects for windows CE??? Could this improve performaces??


thanks!!
