Description
tuned-adm is utility for switching profiles. At the moment we have seven profiles. Every profile has different values for setting up the environment for special tasks. We'd like to have tested all of them even if some of them can't have better results on laptop. In case you don't want measure them all then please measure at least the first two profiles designed for laptop.
* laptop-battery-powersave - saving the battery maximally * laptop-ac-powersave - settings for laptop on adapter (occasionally discharging battery)
These two should show differences.
* spindown-disk - lower spins of disc, quiet and effective on laptop and server * default - basic settings
The other settings are self descriptive and we'd like to have them also measured on your laptops, even if doesn't show the best numbers. It's only for our comparison.
* desktop-powersave * latency-performance * server-powersave * throughput-performance
How to test
- prerequisite: measure bltk in reader mode
- tuned-adm list - will list all profiles which could be set
- tuned-adm profile laptop-battery-powersave
- measure with bltk -R -n 4
- tuned-adm off
This command switch your system back to previous setting without tuned and other features.
We can test the same way also these profiles: spindown-disk, default. The other profiles probably
won't have good results because they suppose different load of system.
Expected Results
- file from bltk
