Install software cpufrequtils
1. untuk melihat nilai scaling_governor sebelumnya per CPU, jalankan perintah:
sudo apt-get install cpufrequtils -y


Edit cpufrequtils
  cat /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor
sudo nano /etc/default/cpufrequtils
 
Tambahkan pada nano, kemudian simpan
GOVERNOR="performance"


Restart cpufrequtils
powersave
  sudo update-rc.d ondemand disable
powersave
  sudo /etc/init.d/cpufrequtils restart
powersave
powersave
powersave
  powersave
  powersave


Cek apakah CPU Governor sudah mode Performance
...
cpufreq-info


Atau
2. untuk set scaling_governor ke "performance" mode untuk setiap CPU, jalankan:


  echo performance > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
  echo performance > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
Line 25: Line 23:
  echo performance > /sys/devices/system/cpu/cpu6/cpufreq/scaling_governor
  echo performance > /sys/devices/system/cpu/cpu6/cpufreq/scaling_governor
  echo performance > /sys/devices/system/cpu/cpu7/cpufreq/scaling_governor
  echo performance > /sys/devices/system/cpu/cpu7/cpufreq/scaling_governor
...
3. Untuk verifikasi konfigurasi jalankan kembali:


  cat /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor
  cat /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor
