#hash #performance #benchmark in #JS. MurmurHash gets 14k ops/sec in my Firefox; MD5 only 687; SipHash only 1589; and the equivalent of Java string hashCode() 12k.
#hash #performance #benchmark including Murmur2, Murmur3, CRC-32, FNV-1a, but not SipHash yet and actually no “secure” hash functions like MD5, SHA-2, or Keccak.
#performance of the Murmur3 #hash is about 1.68 bytes per cycle, 5 gigabytes per second on a core of a 3GHz Intel Core 2 Quad Q9650, as of 2011.
