FWIW, I changed Murmur3/32 to xxhash/32 and here are results
---
murmur3
[cyrill@grain cbox] ./hvsrb --mh
mh create diff : 459890 ns
mh lookup diff : 194201 ns
xxhash
[cyrill@grain cbox] ./hvsrb --mh
mh create diff : 421618 ns
mh lookup diff : 123385 ns
lookup works almost twice faster on random data,
creation time is comparable.
