Calculate the average CPU frequency over a time period. Requires root privileges. More information: https://manned.org/cpufreq-aperf.

  • Start calculating, defaulting to all CPU cores and 1 second refresh interval:

sudo cpufreq-aperf

  • Start calculating for CPU 1 only:

sudo cpufreq-aperf {{[-c|--cpu]}} {{1}}

  • Start calculating with a 3 second refresh interval for all CPU cores:

sudo cpufreq-aperf {{[-i|--interval]}} {{3}}

  • Calculate only once:

sudo cpufreq-aperf {{[-o|--once]}}
