    I find "nice -n -12" to be easier to remember and more intuitive than the double hyphen (nice --12) and prevents accidentically using the positive number instead of negative.
    With normal user privileges, you can't usually use a negative niceness.

      Yeah I have:
      Code:
      myusername  -  nice  -20
      in /etc/security/limits.conf which allows it to be changed. Also required for Feral's GameMode for it to change niceness.

        I did say "usually". If someone doesn't know what they're doing, they're not going to accidentally swamp the CPU. But, if you give yourself permission, of course you can shoot yourself in the foot.

        Edit: And, speaking of shooting yourself in the foot, I wouldn't go all the way to -20. IMO, -8 should be fine. Even if you have background work going on, just increase its niceness.

          Right on, makes sense for it to be the default. I only mentioned it in case someone else didn't know, as your post was clear since you used normal and usually.

            That $999 Sandy Bridge would cost $1140 in today's dollars.

            But also, the depreciation left of that same Sandy Bridge in 2019 is down to zero.

            The average used price now is $99.

            Since AMD didn't have anything to counter at the time, it's value was somewhat maintained.

            Now that Zen is out, it clearly shows how badly Intel was overpricing even then.

              Huh? How does Zen show that?
