    I did not say it was increased to improve interactivity response - and
    it certainly has little or nothing to do with kernel preemption being
    merged.

    I suspect a big benefit would be poll/select performance. I think this
    is why RedHat increased HZ in their kernels.

    You would have to ask Linus exactly what his intentions were.
