Donald Knuth made the following two statements on optimization:
 - "We should forget about small efficiencies, say about 97% of the
time: premature optimization is the root of all evil"
 - "In established engineering disciplines a 12 % improvement, easily
obtained, is never considered marginal and I believe the same
viewpoint should prevail in software engineering"
