Do you have any pointers to benchmarks that show this? The SipHash paper
shows significant performance

The main selling point of SipHash is that it's faster than normal
crypto hashes for short messages. Since ZFS almost always hashes long

If that is all you want, have you considered SipHash? It is much faster
than the other algorithms, yet more secure than CityHash, Murmurhash and
friends. And it provides an IV/salt to make it per instance unique.
Is SipHash really that fast in this context? AFAIK it's only much
faster for
