Alex D Herbert created RNG-75:
---------------------------------

             Summary: Improve the speed of the RandomSource create method.
                 Key: RNG-75
                 URL: https://issues.apache.org/jira/browse/RNG-75
             Project: Commons RNG
          Issue Type: Improvement
          Components: simple
    Affects Versions: 1.3
            Reporter: Alex D Herbert
            Assignee: Alex D Herbert
             Fix For: 1.3


Update the {{o.a.c.rng.simple.internal}} package to improve the construction speed of random generators.

Areas identified by the construction benchmark [RNG-72|https://issues.apache.org/jira/projects/RNG/issues/RNG-72] include:

* Update the {{RandomSourceInternal}} to know the desired size for the native seed
* Update the {{SeedFactory}} for faster {{byte[]}} conversions
* Remove the use of reflection for fast seeding generators

It is intended that all changes made are non-destructive to the quality of any generated seed.
