For VAX-11/780 see the benchmark results and source code from Kashtan's 
research.  AUUGN-V02.4.pdf starting on PDF page 24. And see Joy's 
followup in AUUGN-V02.3.pdf (PDF Page 60). See

While your OS may be different it has numbers for some different 
systems so may give you some rough estimates. If this code isn't online, 
it would be nice to make available (maybe put on github and let us 
know).

(Hopefully someday soonI will get my book completed that has this 
story.)
