  • robin-hood-hashing

    Discontinued Fast & memory efficient hashtable based on robin hood hashing for C++11/14/17/20

    • std::unordered_map is notoriously slow, several times slower than a "proper" hashmap implementation like Google's absl or Martin's robin-hood-hashing [1]. That said, std::sort is not the fastest sort implementation, either. It is hard to say which will win.
