Cpu runs at lowest frequency even under heavy load. I have to manually set frequency using cpufreq-set.

So far I have always had good experiences with tlp:

      services.system76-scheduler.settings.cfsProfiles.enable = true; # Better scheduling for CPU cycles
      powerManagement.powertop.enable = true; # enable powertop auto tuning on startup
      services.power-profiles-daemon.enable = false; # Disable GNOME's power management
      services.tlp = {
        enable = true; # Enable TLP (better than gnome's internal power manager)
        # sudo tlp-stat or sudo tlp-stat -p
        settings = {
          CPU_BOOST_ON_AC = 1;
          CPU_BOOST_ON_BAT = 1;
          CPU_HWP_DYN_BOOST_ON_AC = 1;
          CPU_HWP_DYN_BOOST_ON_BAT = 1;
          CPU_SCALING_GOVERNOR_ON_AC = "performance";
          CPU_SCALING_GOVERNOR_ON_BAT = "powersave";
          CPU_ENERGY_PERF_POLICY_ON_AC = "performance";
          CPU_ENERGY_PERF_POLICY_ON_BAT = "balance_power";
          PLATFORM_PROFILE_ON_AC = "performance";
          PLATFORM_PROFILE_ON_BAT = "balanced";
          START_CHARGE_THRESH_BAT0 = 75;
          STOP_CHARGE_THRESH_BAT0 = 81;
        };
      };
