    The buffer hash you are using looks very slow in computing the hash even
    if it may be the fairest in the math world.

    It's 10 instructions, cut me a break, cache/tlb misses on load
    instructions due to a mediocre hash cost several orders of magnitude
    more than these 5 measly cpu cycles.

    "very slow" indeed...
