I just borrowed a power meter to see (or not to see) real effects of
dyntick. The difference between static 1000 HZ and dynamic HZ is much
less than I expected, only a very little about noise. With dyntick
disabled at 1000 HZ my laptop needs 31,3 W. With dyntick enabled I
get 29.8 W, the pmstats-0.2 script shows me that the system is at
35-45 HZ when it is idle.
The power consumption difference between 250 HZ static and dyntick is
below the noise, so maybe hardly worth all the struggle.
I think it's the other way round, we have the lower power without the
higher latency. At least as I can measure...
Bravo to all concerned to get this to the testing stage!
