The new version finally is in svn :-) The new results and comments can be
found at

http://people.netfilter.org/kadlec/hashtrie

A short summary:

- sfhash does indeed faster than jhash when CPU-dependent optimization is
  enabled
- hastrie with variable hash sizes at the different level can help,
  surprisingly both in memory and speed. I tested three variants, there
  may easily be other ones which are even better.
- hasharray is very good on the price of some memory. But very good,
  and simple.

Best regards,
Jozsef
