This is a naive benchmark used for regression testing only. We divide right down to twopoint vectors and construct the result using copying append. A production algorithm would switch to an inplace sort once the size of the vector reaches a few thousand elements. 135 Sort a vector of doubles by recursively splitting the vector and sorting the two halves.
