Hi:

Based on my experience with GTK+, widgets drawing could be more slow because
all widgets are double-buffered, however, if you're not interested in 
that feature,
you can always use gtk_widget_set_double_buffered() to disable it.

Pango is very slow, and I don't know any way to improve speed. May be 
the new
Pango libraries with cairo support would help, but I'm not sure at all. 
You could
directly use Xlib font drawing.

However, not all is "slowliness" with GTK+, some operations with glib, 
and some
GTK+ widgets perform better than, for example the equivalent QT ones.

Depending on the kind of project you want to develop, you will find 
advantages or
disadvantages using GTK+.

Regards,

D. Campos
