Loads!
Lower security is nearly always faster, but you will have to do some timing tests yourself.
Of you aren't interested in security, then there are loads of ways to hash stuff: MD5, CRC, even XOR and SUM.
What you want too use will depend on your data, and how big your hash has to be - bigger means fewer false matches. Have a look at this:
