Subject: [ANNOUNCE] DeskOpt - on fly task, i/o scheduler optimization

Hi,

Here is something that might be useful for gamers and audio/video editors
http://www.stardust.webpages.pl/files/tools/deskopt/

You can easily tune CFS/CFQ scheduler params

sched_batch_wakeup_granularity_ns
sched_latency_ns
sched_min_granularity_ns
sched_runtime_limit_ns
sched_stat_granularity_ns
sched_wakeup_granularity_ns

back_seek_max
back_seek_penalty
fifo_expire_async
fifo_expire_sync
quantum
slice_async
slice_async_rq
slice_idle
slice_sync

+ nice levels

* default class for games

DeskOpt has many design flaws, but it works for me :)

Michal
