This is not a laptop so I don't have any power management beyond screen blanking enabled. Why would I want to limit the CPU?
This is not about limiting the CPU, it is about saving power when the CPU is idling, reducing heat and power consumption (saving you some money and being environmentally friendlier, together with prolonging CPU life). If you use the ondemand or conservative governor the CPU will not be limited, but clock itself according to CPU load. It may even be possible that (depending on your CPU model) Turbo Boost/Turbo Core will not work when the CPU can not choose the clockspeed for the cores itself, so that the performance mode is limiting your CPU.

Perhaps I should make a new thread as I certainly don't want to hijack this one, even if it does perhaps show the value of having various systems monitors on the desktop, but I am aware of course of cpuidle and it is enabled in my custom kernel. Oddly, even though I see that "upower" is apparently running (at least it has a pid even if accompanied by a "?") but when I use the KDE System Settings > Power Management everything is greyed out and it tells me
" Power Management configuration module could not be loaded. The Power Management Service appears not to be running. This can be solved by starting or scheduling it in 'Startup & Shutdown' " While upowerd is not in that list it is apparently running. Suggestions?
