  This will probably change as we get more cores and performance/efficiency ones. Macs already run a lot of the low-priority tasks on their slow cores leaving the fast ones available for interactive activities. I don't disagree on the current approach though. If I start a, say, long build job from a terminal window, I have control over the resources it can take. If, OTOH, I start a program from the GUI, it's reasonable to assume I want it to have full control, at least while it has the focus. Now, letting the GUI dynamically renice non-focused processes would be very nice.

    More cores won’t fix it. Some app will add more processes and use all available CPUs and there’s no reservations. You had it right with nice - phones and tablets and consoles and cars have it right with their techniques. Apps shouldn’t be able to make the system unusable by default.

      > More cores won’t fix it. By themselves, no, but there are limits to how many cores a workload can keep fed. You'll see declining returns at high core counts (which is one of the reasons we don't have Xeon Phis these days).
