Ugh. This looks like a poster child case for a benchfarm ...

Is there any chance you guys could triangulate this a bit? Good initial 
triangulation points might be the end of each commitfest. (I have a 
vested interest in making sure COPY performance doesn't regress, since 
it will affect parallel restore's speed in spades.)
