You could just profile this program:
int main (int argc, char **argv)
{
gtk_init (&argc, &argv);
exit (0);
}
The equivalent for GNOME is a bit more complex (and probably wastes a
fair bit more time).
It's probably a better measure if you create a window, rather than just
the init, since some things are done lazily:
int main (int argc, char **argv)
{
GtkWidget *window;
GtkWidget *button;
gtk_init (&argc, &argv);
window = gtk_window_new (GTK_WINDOW_TOPLEVEL);
button = gtk_button_new_with_label ("Hello");
gtk_container_add (GTK_CONTAINER (window), button);
gtk_widget_show (button);
gtk_widget_show_now (window); /* blocks in mainloop until window
has been mapped by X server */
exit (0);
}
That should be a good measure of how long it takes GTK + X server to get
a minimal window on the screen.
One thing we know takes time is loading stock icons, so you could make
the button have an icon to add profiling of that issue:
gtk_button_new_from_stock (GTK_STOCK_OPEN);
