Hi Peter,
I'm currently also testing your preemptibility patchset and have to say that on top of 2.6.36-rc3 it really seems to make a positive difference for me :)
since I'm only a regular (power)user utilizing linux-distributions for my everyday work I can report only about that:
- the desktop stays very responsive even during copying, backing up and transferring of large amounts of data (e.g. backing up 1 TB of data via rsync between different filesystems); this includes the GUI staying responsive, the mouse not lagging and apps opening up almost instantaneously - there is very little to no noticable lags or repetitions when hearing webradio or audios during longer periods of time - and much more
considering that 2.6.36 received several other improvements in this area - http://lkml.org/lkml/2010/8/1/40, the patches from Wu Fengguang and KOSAKI Motohiro - concurrency managed workqueues - and other performance improvements, especially VFS may also add up to this
anyways: please consider adding this to next/mainline during the next merge cycle
my linux-desktop didn't feel that reponsive for a long time ! ^^ if I recall correctly if felt comparably responsive when I used Con's RSDL or SD scheduler - CFS and CFQ have made great progress in terms of desktop usage, interactivity and delays
Regards and thanks to everyone involved in the continued improvements in this area
Mat
