In the BIOS, all settings are on "Max performance".
However, we cannot check it from OS level:
SERVER413:~ # for i in /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor; do cat $i; done cat: /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor: No such file or directory SERVER413:~ #
We want the server to always run on "max" performance.
Q: Does this mean that the server will always run on max performance?
If CPU scaling would be supported, it would only downscale the CPU, no?
If we check, what MHz is it running, it is running at:
SERVER413:~ # grep -E '^cpu MHz' /proc/cpuinfo | sort -u cpu MHz : 2294.633 SERVER413:~ #
SLES 11.4. Although there is some "turbo frequency" mentioned on ark.intel with 3.1 GHz...
