    Block transfer sizes over about 64kB are totally irrelevant for 99% of all

    Don't even bother testing anything more. Yes, bigger transfers happen, but
    a lot of common loads have *smaller* transfers than 64kB.

    So benchmarks that try to find "theoretical throughput" by just making big
    transfers should just be banned. They give numbers, yes, but the numbers
    are pointless.
