### 3.5- Windows Benchmark

> These results are obtained from complex benchmarks, not included in the library because they use non free software. (If you are interested in the details, contact fjtapia@gmail.com)

> There are 3 types of benchmarks,

> > - 64 bits integers
> > - strings
> > - objects of several sizes.

> > The objects are arrays of integers. The heavy comparison sums all the elements in each, and the light comparison uses only the first number of the array.

> > This benchmark ran on a VirtualBox virtual machine with 8 threads and 16 GB of RAM, running over a Intel(R) Core(TM) i7-5820K CPU @ 3.30GHz with 6 cores and 2 threads by core, and 15M of cache.

> ##### OBJECTS RANDOMLY FILLED

> > The objects are arrays of 64 bits numbers

> > They are compared in two ways :

> > > (H) Heavy : The comparison is the sum of all the numbers of the array.

> > > (L) Light : The comparison is using only the first element of the array, as a key
