I didn't do performance tests compared to the other competitors. The size of the neighborhood (NeighborhoodSize) must be > 0 and <= 62 if StoreHash is false. Rename CMake project name from tsl_hopscotch_map to tsl-hopscotch-map for coherence with the convention used by most package managers.

This benchmark compares different C++ implementations of hashmaps. tessil’s maps: Tessil has done lots and lots of work on hashmaps, in all kinds of flavours. . It is also well suited for implementing a concurrent hash table.

STL map 编程过程中难免要使用 哈希表，Hash是一个非常高效的映射数据结构，另外一种常用的是Map。Hash和Map的区别，是底层的实现，hash一般是数组+散列的思想，而Map一般是红黑树，或者其他的树。 STL中的哈希表有 std::map, std::unordered_map，可以很快找到key对应的Value值。 map底层是基于 红黑树 实现的 Performance benchmark results: here Git repository: tessil/hopscotch-map Hopscotch is also quite performant. I found it when I was looking for something similiar I used once so far a smaller project where it had far more better performance than std::unordered_map.
