I cannot reproduce this kind of performance problem.  I'm going to need 
some help to fix it.  What video card?  CPU?  I did find a minor 
performance issue with window manipulation using x11perf:

	$ x11perf -move

With composite extension enabled, no xcompmgr:

  80000 reps @   0.1137 msec (  8790.0/sec): Move window (4 kids)

With composite extension disabled:

 240000 reps @   0.0210 msec ( 47700.0/sec): Move window (4 kids)

I'm building the server -pg to find out where this problem lies.  But, 
first I'm fsck'ing all my disks again (having crashed about 50 times 
yesterday helping Eric Anholt work out an R200 DRI bug).
