| |
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.
