Subject: [ANNOUNCE] DeskOpt - on fly task, i/o scheduler optimization
Date: Fri, 31 Aug 2007 17:35:38 +0200 [thread overview]
Message-ID: <46D8354A.3030208@googlemail.com> (raw)
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
Results from Nexuiz benchmark
|-------------------------------------------------------------------------------------------|
| | CFS + CFQ | CFS + CFQ + DeskOpt * |
|-------------------------------------------------------------------------------------------|
| timedemo demos/demo2 | 41,395896833 fps | 41,460051233 fps |
| timedemo demos/demo2 + massive_intr 4 1000 | 18,343223633 fps | 37,814504933 fps |
| timedemo demos/demo2 + massive_intr 8 1000 | 9,334974533 fps | 37,376611267 fps |

* default class for games
DeskOpt has many design flaws, but it works for me :)
Regards,
Michal
