Out of curiosity, do you have any performance metrics comparing Xlib to xcb in QT?  If not, was there a build of QT during development which enabled a choice between xcb and Xlib which could be used for such metrics?  Most comparisons I've seen have been with various small utility apps.  It would be nice to have some "real world" numbers to back up our claims to awesomeness.
