profile with render disabled

I disabled Render inside cairo-xlib-surface.c and my application returned to
decent speed (i.e. doesn't feel like swimming through mud) even on Apple X11. I
guess the X server doesn't matter much now, its top activity now is memcpy.
This configuration has the advantage that one can see clearly what's going on
and it's great that pixman is a mini-fb and has even the same function names.
I produced  a new profile with the main culprits. This is again operating the
UI of my application, which is nothing fancy (some comboboxes, an expander with
some sliders, a textview where short messages are displayed, a menu, a file
chooser, an aboutbox). I hope it is useful for you.
You can see that most of the requests come from GDK (and not from Pango,
sorry), in particular from gdk_window_clear_backing_rect, I suppose this is in
the GDK double-buffering.
