As a matter of habit, when I rebuild stuff (which I do semi-regularly,
not scripted etc.) I make sure to log the times with time(1) and print
the rusage struct (-l option.)
That is, essentially
$ /usr/bin/time -l make -j 15 buildworld > buildworld2.log 2>&1 &
The tail end of my latest 11.0-STABLE:
--------------------------------------------------------------
>>> World build completed on Thu Jan 5 18:04:23 CET 2017

Ironically I can't provide you with historic ones (from 10.3, 10.1, 9
etc) because some weeks ago I finally garbage-collected old source
trees.
