Forgot to mention about doing parallel make jobs.  This is detailed in
the book in "4.5. About SBUs" but I would just add that it is worth
doing as it has potential to greatly speed things up.  You can try the
SBU build time with different values for '-j'/'--jobs'; a value of the
number of CPUs you have should be good value.  If you just do a plain
'-j' without a number then GNU make will do an unlimited number of
parallel jobs; which, while interesting to watch, will probably be
slower than a value of the number of CPUs on the host.  If you do have a
problem with building a package then try dropping the parallel make jobs
for it.
