If you need ultimate speed you can experiment with other hash implementations
(unordered_map, dense_hash_map from google-sparsehash, etc.). Also those
implementations allow you to change hash function, so you have a plenty of possible
combinations ;)

if you have fixed set of string keys, you can try to generate perfect hash function for it
using one of existing tools.
