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.
