NAME
Digest::MurmurHash - Perl XS interface to the MurmurHash algorithmSYNOPSIS
use Digest::MurmurHash qw(murmur_hash); murmur_hash($data_to_hash);
OR
use Digest::MurmurHash; Digest::MurmurHash::murmur_hash($data_to_hash);
DESCRIPTION
The murmur hash algorithm by Austin Appleby is an exteremely fast algorithm that combines both excellent collision resistence and distribution characteristics.This module requires Perl version > 5.8
BENCHMARK
Here is a comparison of this module between common hash function modules on an Intel Core2Duo 2.4GHz machine.n = 10000000 murmur : ( 2.54 usr + 0.01 sys = 2.55 CPU ) @ 3921568.63/s jenkins : ( 2.89 usr + 0.01 sys = 2.90 CPU ) @ 3448275.86/s pearson : ( 2.99 usr + 0.01 sys = 3.00 CPU ) @ 3333333.33/s fowler : ( 3.30 usr + 0.01 sys = 3.31 CPU ) @ 3021148.04/s crc32 : ( 3.86 usr + 0.00 sys = 3.86 CPU ) @ 2590673.58/s md5 : ( 7.12 usr + 0.01 sys = 7.13 CPU ) @ 1402524.54/s sha1 : ( 9.86 usr + 0.01 sys = 9.87 CPU ) @ 1013171.23/s
