Sure.

Note that I didn't say that, nor do I believe it. I just listed things
that *contribute* to the overall slowness (usually more than you'd
think).

That's the part which needs profiling. In order to fix GTK+ to be
blazingly fast, you'd need to figure out where exactly it is slow.
That is somewhat hardware dependant, since different hardware has
different areas where they suck, so you will not find a single answer
anywhere.

Any effort to "make it work fast" (where "it" might be GTK+, Pango,
cairo, etc) would be highly appreciated of course, there's even a
dedicated list for that (though it spans more than just those
mentioned and has been sadly somewhat quiet lately):
