One last tweak for perfection.

What kernelthreads _needs_ to run? So I can put them on max pri renice, 
along with reniced X and app. And everything else on idle priority. So 
to make the app run at max efficiency, and not be starved by 
kernelthreads waiting. (Or any other consideration, for giving maximal 
cpu to app. Even small tweaks.)

To read my research so far, (and I have done much, about 2 years of 
tweakin´ on and off.) Please see

Main points, no highres timer, 90hz timer, + a lot of smaller tweaks. 
This makes an amazing linux-desktop, for gaming, video and audio. The 
popular computer for everyman. Also boosts performance, for 
resource-constrained systems.

For more advanced hacking, one could also get in there, and make several 
HZ timers, extremely low ones, for the components who only require that, 
and 90hz for video-components, for instance (low video/frame jitter), 
and higher if anything should require that.

Also system-wide, software should be synced to hz, if required for 
lowest jitter, such as animations and videoplayers, and videoplayers 
automatically change refresh rate to a multiple of video framerate.

Peace Be With You.
