I did some profiling on my 945GM powered laptop with Rawhide (F9-Beta
+ updates), X.Org X Server and  xf86-video-intel-2.3-rc2:

1.) Window resizing is "awful" slow for large (~1000x1000) windows.
This was done resizing Dolphin:
413755   45.5420  libc-2.7.90.so           libc-2.7.90.so           memcpy
157667   17.3544  no-vmlinux               no-vmlinux               (no symbols)
104342   11.4849  libexa.so                libexa.so                (no symbols)
42564     4.6850  libQtGui.so.4.3.4        libQtGui.so.4.3.4        (no symbols)

2.) Text is quite slow, with EXA i am able to get ~160.000 glypgs for
aa10text, with EXA I only get ~90.0000g/s. However on my system it
looks like its not the drivers fault:
99090    38.2382  libexa.so                libexa.so                (no symbols)
46133    17.8024  intel_drv.so             intel_drv.so
27354    10.5557  Xorg                     Xorg                     (no symbols)
21857     8.4345  intel_drv.so             intel_drv.so

I did not change any defaults (MigrationHeuristics, ...) for both profiles.
