Traffic Shaping Worse Than Baseline?
-
Is any part of the PRIQ queue processing offloaded in a manner which HFSC is not? Could there be a situation where I am hitting processing limits of an offloaded resources which are not reported as part of the main CPU statistics?

I don't think the shapers use any offloading, but they make use of certain driver features

The CPU needed for any sched algo will be minimal. Elegance and efficiency are perhaps more important than actual scheduling capability (Stochastic Fair Scheduling, for example). HFSC, perhaps the most complex and CPU intensive, was capable of 80,000+ packets per second on a 200Mhz Pentium Pro.
