FWIW, I changed Murmur3/32 to xxhash/32 and here are results
[cyrill at grain cbox] ./hvsrb --mh
mh create diff :               459890 ns
mh lookup diff :               194201 ns

[cyrill at 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.
