If new17 is very close to jhash/jhash2 then the cycles comes into play.
Anyway, there is already a very potent hash interface in form of jhash{,2}.

PPS: http://libhashish.sourceforge.net/ have some real hash benchmarks in form
of avalanche test and some others too. It does not really matter here because
Jenkins performs _nearly_ perfect in all cases. ;)
