こんにちは! This implementation sorting int is very fast, but do you have tried string or struct?
In this case, std::sort is faster in VS2015 from my test result

Hi Baobaobear

Msvc's std::sort and std::stable_sort seem to have very interesting implementations.
The sort algorithm is deep, so it's worth exploring.
