Description
Note: This might be an issue only on non-virtualized systems (with processors that support variable frequency)
facter 3
$ /usr/bin/facter processors.speed
|
4.20 GHz
|
facter 4 (2 consecutive queries)
$ bundle exec facter processors.speed
|
3.18 GHz
|
$ bundle exec facter processors.speed
|
1.06 GHz
|
Facter 4 reads from /proc/cpuinfo which reports the current speed of the processors:
$ grep 'cpu MHz' /proc/cpuinfo
|
cpu MHz : 1724.163
|
cpu MHz : 1899.271
|
cpu MHz : 2135.291
|
cpu MHz : 1625.782
|
cpu MHz : 1729.682
|
cpu MHz : 1817.039
|
cpu MHz : 1729.482
|
cpu MHz : 1993.369
|
Facter 3 reads the max speed from the first CPU (in kHz, then converts it):
$ cat /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_max_freq
|
4200000
