I think you are using the right library. The problem is really just
that the text sample was so small that Pango spent a lot of time
building caches etc.

Loading files is not a good benchmark to profile, because loading
files is actually quite fast. As I also said on IRC, I think the real
reason Scintilla feels slow during scrolling is that it redraws the
entire window every time the scroll bar moves. 

You should probably look into using gdk_window_scroll() to only draw
the small strip that is brought in from off-screen.
