Kecepatan Pasti saja merupakan kebutuhan yang sangat penting bagi kita dalam dunia komputer, nah oleh karena itu saya mencoba untuk berbagi ilmu tentang cara memaksimalkan kinerja CPU di Ubuntu, ini sama halnya dengan overcloking yang sering kita dengar di windows, okdeh kita to the point aja langsung.
yang perlu kalian persiapkan adalah :

  1. install “cpufreqd” : sudo aptitude install cpufreqd
  2. sudo lsmod | grep cpufreq , dan anda akan melihat output seperti dibawah ini root@goesary-laptop:/home/goesmvn# sudo lsmod | grep cpufreq
    acpi_cpufreq           15500  1
    cpufreq_userspace      11396  0
    cpufreq_stats          13188  0
    cpufreq_ondemand       14988  0
    freq_table             12672  3 acpi_cpufreq,cpufreq_stats,cpufreq_ondemand
    cpufreq_conservative    14600  0
    cpufreq_powersave       9856  0
    processor              42156  4 acpi_cpufreq,thermal
  3. Edit file cpufreqd di : sudo vim /etc/cpufreqd.conf, pastikan backup telebih dahulu file ini
