I also experience poor i915 performance, I'm running latest jaunty packages
with no help to the issue.
Performance is poor everywhere, glxgears, mplayer, flash and compiz all show
poor performance,
mplayer and flash to the level that I can't comfortably watch videos.
libdrm-intel1 is installed.
I'll attach Xorg.0.log.
