-_The measurments above have been done using default runners provided by GitHub Actions. It's important to note that in the context of pure-rand as in most of the libraries dealing with random, in addition to generate random values based on rock-solid random number generators, we also make sure to generate them out of uniform distributions which is not the case for the native case._
