The issue was indeed font initialization. I commented out the line in
void QWindowsFontDatabaseFT::populateFontDatabase()
that populates the font database with all system fonts. Now Qt only loads the 
family of the default font at start-up.

I guess you are on to something. But then why does my Qt Widget application 
start fast enough.

Is there a way to make Qt Quick do text like Qt Widgets?



Try this:
renderType : enumeration

Override the default rendering type for this component.
Supported render types are:
*         Text.QtRendering - the default
*         Text.NativeRendering
Select Text.NativeRendering if you prefer text to look native on the target 
platform and do not require advanced features such as transformation of the 
text. Using such features in combination with the NativeRendering render type 
will lend poor and sometimes pixelated results.

Nice catch. My wild guess is font initialization.

I am thinking that the issue is not the loading of the dlls. Because Widget 
application and Qt Quick Rectangle application loads fast enough.
The issue is not parsing QML. These sample QML files are just a few lines long.
It is not the instantiation of the Text item. Because adding a second Text item 
is instant.
So what can it be?
