Symptom & Impact

Latency and throughput regressions appear after system updates or role changes.

Environment & Reproduction

A generic or powersave tuned profile is active on a workload requiring throughput tuning.

Root Cause Analysis

Run tuned-adm active, tuned-adm recommend, and review CPU governor settings.

Quick Triage

Enable tuned service with sudo systemctl enable –now tuned if it is not running.

Step-by-Step Diagnosis

Apply a suitable profile such as throughput-performance using tuned-adm profile.

Solution – Primary Fix

Benchmark workload metrics and compare before and after profile adjustments.

Solution – Alternative Approaches

Confirm profile persists across reboot and systemctl status tuned remains healthy.

Verification & Acceptance Criteria

Return to prior profile if thermal or energy policies are violated by aggressive tuning.

Rollback Plan

Map tuned profiles to server roles in architecture standards and provisioning code.

Prevention & Hardening

Track performance baselines and detect drift after profile or kernel changes.

Related Errors & Cross-Refs

Set tuned profile declaratively with system roles and verify in post-deploy checks.
