CRC32-C (a kind of crc32 with a polynomial 0x82F63B78), he is the fastest on new Intel Ah because the set sse4.2 includes instructions for its hardware support. On other processors it speeds crc32 usual, ie is also very fast.

There is still a lot from the implementation of the algorithm depends, for example, in the hash function built into PHP, the fastest algorithm md5, and crc32 is almost 2 times slower, and the same adler32 4 times slower, although the descriptions in the same wiki should be one of the fastest times as adler32.
