After installing Ubuntu on my legacy laptop, i noticed that the CPU frequency is scaling down to 800 Mhz. (upon to the temperature i guess)

derya@dsezenlinux:~$ cat /proc/cpuinfo

processor : 0
vendor_id : GenuineIntel
cpu family : 6
model : 23
model name : Intel(R) Core(TM)2 Duo CPU T9300 @ 2.50GHz
stepping : 6
microcode : 0x607
cpu MHz : 800.000

When it is 800 Mhz. the computer becomes extremely slow, so i decided to keep it stabile at 2500 Mhz.

Steps:

1. Install cpufreq-selector

For Ubuntu, this is under gnome-applets pack:

sudo apt-get install gnome-applets

2.  Run the following for each core:

sudo cpufreq-selector -c 0 -g performance

sudo cpufreq-selector -c 1 -g performance

3. Check if it is ok:

cat /proc/cpuinfo
