What sort of overhead do you have in mind here?
I'm suspecting you mean the mental overhead to the programmer coding for this, who might complain at having to learn a whole new subsystem (cpusets) just to say how to group CPUs for collecting these stats.

My natural inclination is to disagree with this. Increasingly popular large systems running heterogenous loads benefit from finer granularity policies.
Though I will be honest in acknowledging that I have not studied these taskstats in detail, so my inclinations may be off the mark.
