    Surely you should schedule based on the memory bandwidth at that point ?
    Assuming the data collection overhead is acceptable. A long time ago
    someone did a paper on a related topic (Scheduling by memory bandwidth on
    the grounds that memory not CPU bandwidth was the resource most
    constrained) and that demonstrated that for quite a few processors the
    memory bandwidth data is cheaply available in the profiling registers.
