On my machine, i have power savings disable on the BIOS. When I run Ubuntu on this machine, the CPU's are running maximum at 2100 MHz.However, when I'm running CentOS 7, even with the scaling governor set to performance, the CPU's are not running full at 2100 MHz.cat /sys/devices/system/cpu/cpu*/cpufreq/scaling_governorperformanceperformanceperformanceperformancegrep -i mhz /proc/cpuinfocpu MHz         : 1688.285cpu MHz         : 2058.656cpu MHz         : 1622.988cpu MHz         : 2070.632My application is a network processing application, so the CPU clock difference is resulting a performance difference.I do not have cpuspeed,powerd, or any other power regulating services running. So my question is, is this expected behavior given the cpupower is set to perform?It seems CentOS is override the BIOS setting.When I boot to Ubuntu, it just takes the BIOS settings and all the CPU's are running max.
CentOS 7 cpupower not setting the CPU's to maximum
