When using a "Tuned" profile that contains a "[cpu]" section the processors are unable to reach maximum performance

This document (000020619) is provided subject to the disclaimer at the end of this document.

Environment

SUSE Linux Enterprise Server 15 SP3

Situation

When using a tuned profile the CPU frequency doesn't reach the maximum.

Resolution

This is coming from tuned global attribute dynamic tuning (/etc/tuned/tuned-main.conf).

# Dynamicaly tune devices, if disabled only static tuning will be used.
dynamic_tuning = 1

Change the dynamic_tuning to be 0.
Then stop and start the tuned service.

Cause

Utilizing the one CPU is enough to exceed tuned's "dynamic tuning" load attribute.
