There is no guarantee that suffixing the name of your program with “-top” will endear it to me.
I’m not a power freak; I get no pleasure from tuning the power consumption on a 12-year-old laptop. But I do enjoy seeing what uses what, where the system priorities are, and — in a bit of a twist — to be able to toggle a few switches and adjust behavior.
That powertop does in its far right tab, the aptly-named “Tunables.” If you need to manhandle the settings on your machine, you could check out what’s available there. I’m afraid I have no advice in that respect.
But it is fun to poke around with them. 😉
