Re: [PATCH] i386 No-Idle-Hz aka Dynamic-Ticks 3

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.
