Make and submakes have been gone over already. See <URL:

I'm not sure it can be applied to the ports tree, though. I haven't
looked into it, but recalled this paper when you mentioned measuring
makes and sub-makes.
Unfortunately you deleted the sentence before, so I rephrase it: before
looking into optimizations find out where the time is actually spend -
how many seconds of the hours the process takes, are actually spent in
make and sub-makes. If the entire process takes 2 hours of which the
makes take 20 seconds then by enhancing performance of make by 50% you
win 10 seconds. This is probably not worth a single line of additional code.
The paper you point to talks about something entirely different.
