Just a "me too". I noticed a huge increase in time for portupgrade when I started using the modular Xorg ports tree and upgraded to X.org 7.2RC. The number of installed ports on my machine went from just over 300 to well over 600 as a result of the upgrade. Specifying small numbers of ports (without globbing) to portupgrade doesn't seem to take much more time, but "portupgrade -a" or anything similar takes forever now. If there is an optimization to be made there it would be good to do it before modular xorg hits the official tree.
