Code review comment for lp:~smspillaz/compiz-core/compiz-core.work_923683

Tested revision 2994. Moving windows is still so slow it's unusable (under valgrind). We should fix this because it's a good indication that the same would occur in the wild on a slow machine.

compiz is spending 70% of it's CPU in or below moveHandleMotionEvent. The two main CPU hogs are:

(73% of the 70%)
moveHandleMotionEvent
CompWindow::move
DecorWindow::moveNotify
DecorWindow::computeShadowRegion

(16% of the 70%)
moveHandleMotionEvent
CompWindow::move
CompWindow::configureXWindow
PrivateWindow::reconfigureXWindow
