In all of the following tables, the best performing result in each row, is
|
||
|
|
assigned a relative value of "1" and shown in bold, so a score of
|
||
|
|
"2" means <span class="emphasis"><em>"twice as slow as the best performing result".</em></span>
|
||
|
|
Actual timings in nano-seconds per function call are also shown in parenthesis.
|
||
|
|
To make the results easier to read, they are color-coded as follows: the best
|
||
|
|
result and everything within 20% of it is green, anything that's more than
|
||
|
|
twice as slow as the best result is red, and results in between are blue.

Result were obtained on a system with an Intel core i7 4710MQ with 16Gb RAM
|

|

and running either Windows 8.1 or Xubuntu Linux.

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