First of all, please also attach the full Xorg.0.log.
I haven't played with xcompmgr recently, but I have noticed that with KDE4,
compositing is much slower with the XRender backend than with GLX. That's not
the case with the intel driver on an i945G though, so for now let's assume this
is a driver issue.
As for the profile, it would be interesting to get more useful symbol
resolution for the 'radeon' image - I presume that refers to the radeon DRM
kernel module. Also, are you sure the vmlinux symbols are accurate? I'm not
sure why vsscanf and dma_alloc_coherent would be such hot spots for moving
around windows. You did reset the oprofile samples before profiling the
operation, didn't you?
