I have a temptation to ask: why hash in the first place?


back in the day, the kiddies had sport by sending RSTs against BGP
sessions.  pretty much any hash with a key space of 48+ bits was
sufficient to raise the bar.  md5 was cheap and easy.

re performance, you may find rfc 1810 amusing, if only from a historical
perspetive.
