  • Switch to TuneD:

    • Replaces cpupower with TuneD to handle CPU governor settings.
    • Applies the throughput-performance profile for enhanced system performance. 
      •      throughput-performance
     Profile for typical throughput performance tuning. Disables power saving mechanisms
     and  enables  sysctl  settings that improve the throughput performance of your disk
     and network IO. CPU governor is set to performance and CPU energy performance  bias
     is set to performance. Disk readahead values are increased.
    • Ensures TuneD is installed, enabled.

  • Kernel Version Management:

    • Checks and validates kernel version, failing if it’s below the required version.
    • Pins kernel packages to prevent automatic upgrades that could disrupt stability.

  • Unattended Upgrades Control:

    • Disables unattended upgrades by modifying configuration files.
    • Removes the unattended-upgrades package to ensure no automatic updates occur.

This is great as is, but I would like to see if we could convert this to using TuneD?
https://ubuntu.com/server/docs/tuned - tuneD with the high throughput option should take care of the governor for us, as well as perform many other system optimizations which enhance overall performance.

Something like

tuned-adm profile throughput-performance

Output check

tuned-adm active

The package installs a service that will manage the profiles automatically once set.

systemctl status tuned.service 
● tuned.service - Dynamic System Tuning Daemon
     Loaded: loaded (/lib/systemd/system/tuned.service; enabled; preset: enabled)
     Active: active (running) since Sat 2024-12-21 09:36:14 CST; 1min 35s ago
       Docs: man:tuned(8)
             man:tuned.conf(5)
             man:tuned-adm(8)
   Main PID: 1779531 (tuned)
      Tasks: 4 (limit: 76595)
     Memory: 16.8M
        CPU: 448ms
     CGroup: /system.slice/tuned.service
             └─1779531 /usr/bin/python3 -Es /usr/sbin/tuned -l -P

Thoughts?

I think switching to TuneD makes a lot of sense, especially with the added benefits for overall system performance. Will take a look into it
