Hi,

what is the point of running tuned as a daemon when dynamic tuning is disabled?

What is the point of enabling dynamic tuning, especially when using the supplied profiles like throughput-performance?

I haven’t customized those by specifying any thresholds, and I don’t see any point in doing things like dynamically changing disk schedulers or CPU governors depending on something recognized by tuned.

Why is there no measurable difference in power consumption between using the powersave, throughput-performance and virtual-host profiles but a very noticeable difference in performance?

The difference in performance appears to depend mainly on which CPU
governor is used. For example, you can make a customized profile from throughput-performance that uses the powersave governor, and performance will be very much as if using the powersave profile.

Since there is no measurable difference in power consumption, why would I want to use profiles and/or CPU governors that supposedly save power and decrease performance?
