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.
