30 In all of the following tables, the best performing result in each row, is
31 assigned a relative value of "1" and shown in bold, so a score of
32 "2" means <span class="emphasis"><em>"twice as slow as the best performing result".</em></span>
33 Actual timings in nano-seconds per function call are also shown in parenthesis.
34 To make the results easier to read, they are color-coded as follows: the best
35 result and everything within 20% of it is green, anything that's more than
36 twice as slow as the best result is red, and results in between are blue.
39 Result were obtained on a system with an Intel core i7 4710MQ with 16Gb RAM
40 and running either Windows 8.1 or Xubuntu Linux.

48 As usual with performance results these should be taken with a large pinch
49 of salt: relative performance is known to shift quite a bit depending upon
50 the architecture of the particular test system used. Further more, our performance
51 results were obtained using our own test data: these test values are designed
52 to provide good coverage of our code and test all the appropriate corner
53 cases. They do not necessarily represent "typical" usage: whatever
