Ok.

I added 2 more test-apps to the CVS "devel-1-0" tree (stress1, stress2).
These create 1024 PG_ThemeWidget objects and show them.

stress1 shows them immediately after creation -> ~2500 ms
stress2 adds them to a PG_Widget container -> ~2000 ms

(on my rather slow Celeron 300)
But i found that the most time consuming part is the creation of the
widgets. Displaying them is rather fast. I guess the slow part is
"LoadThemeStyle". 

Maybe you should check the drawing code of your widget.

Hmm. Strange.
Can you create some minimal sample app showing that behaviour ?

No.
