Interresting; for me the performance is acceptable. However, I don't use bitmap fonts, only non-antialiased truetype fonts. I say acceptable, because I still feel the overall desktop experience is slower with xorg-server 1.9.0, but at least it's usable (which it isn't when I used anti-aliased fonts).
FYI, regarding the slow bitmap font rendering; here's the QT bug (closed, so I suppose we'll never see a fix for it): http://bugreports.qt.nokia.com/browse/QTBUG-7255
