CPUs are not working at max frequency even though the "scaling_governor" is set to "performance"
Issue
- CPUs are throttling though the
scaling_governor
is set toperformance
and form the BIOS settings as well. - The
cpuinfo
output shows each core is running at different frequencies lesser than the max capacity, when checked:
# grep -E '^model name|^cpu MHz' /proc/cpuinfo
model name : Intel(R) Xeon(R) CPU E5-2643 v3 @ 3.40GHz
cpu MHz : 3170.500
model name : Intel(R) Xeon(R) CPU E5-2643 v3 @ 3.40GHz
cpu MHz : 1953.671
