People are generally saying 2D goes faster without the DRI loaded.
That's something I noticed before as well.

Backing store is usually a decelerator. It's out of the picture
when doing something as simple as moving a single window around on the
desktop.

That's likely an issue with your window manager. Raster noticed
the same thing and did some tests and found that most window managers
hiccup when they get events during window moves. You get extra events
if the pointer crosses windows while moving the window. Since title
bars where you grab the window to move it are wide, left-right motion
doesn't cause the pointer to cross window boundaries. Since they
aren't tall, vertical motion does. Sounds unlikely, but that's
alledgely what it is and Raster supposedly solved this problem in
E17.

Mark.
