+ <p class="p">
+ You might use the return value in an application where you perform load balancing, bucketing, or some
+ other technique to divide processing or storage. This function provides a good performance for all kinds
+ of keys such as number, ascii string and UTF-8. It can be recommended as general-purpose hashing function.

+ <p class="p">
+ Regarding comparison of murmur_hash with fnv_hash, murmur_hash is based on Murmur2 hash algorithm and fnv_hash
+ function is based on FNV-1a hash algorithm. Murmur2 and FNV-1a can show very good randomness and performance
+ compared with well known other hash algorithms, but Murmur2 slightly show better randomness and performance than FNV-1a.
