    Well, streams really isn't a very interesting benchmark. It's the
    traditional single-threaded cpu-only thing that just accesses things
    linearly, and I'm not convinced the numbers should be taken to mean
    anything at all.

    The HPC people want to multi-thread things these days, and "cpu/memory
    affinity" is a lot less clear then.

    So I can easily imagine that the performance improvement is real, but
    I really don't think "streams improves by X %" is all that
    interesting. Are there any more relevant loads that actually matter to
    people that we could show improvement on?
