+ | ===== How to disable frequency scaling ===== | ||
+ | This guide explains an easy way to disable **frequency scaling**. | ||
+ | |||
+ | First thing to do is to check the number of CPUs in the system with the command: | ||
+ | <code bash> | ||
+ | ls / | ||
+ | </ | ||
+ | The provided output will be something like this: | ||
+ | <code bash> | ||
+ | cpu0 cpu2 cpuidle | ||
+ | cpu1 cpu3 intel_pstate | ||
+ | </ | ||
+ | and in this case the number of physical CPUs for which we can disable frequency scaling is four, namely '' | ||
+ | |||
+ | With the following script executed by with the //root// privilege: | ||
+ | <code bash> | ||
+ | for i in $(seq 0 3) ; do echo " | ||
+ | </ | ||
+ | we can set the '' | ||
+ | |||
+ | To check that frequency scaling is effectively disabled, you can type many times the following command checking that the frequencies of your CPUs are fixed to the highest values: | ||
+ | <code bash> | ||
+ | cat / | ||
+ | </ | ||
