Subject: Re: [PATCH] sched: Improve latencies under load by decreasing minimum
Date: Thu, 16 Sep 2010 20:48:50 +0200	[thread overview]
Message-ID: <201009162048.50941.ml_kernel@mortal-soul.de> (raw)

Hi.

I don't know if this is relevant but I just tried this ontop 2.6.35.4 while
investigating a different problem and it was quite easy to produce audio
buffer underruns while doing some compile job in the background.

To be exact: I had vlc (1.1 git) play back several flac files and was compiling
qt 4.7 in the background as a test w/ -j5 on an i7 860 . The result was that w/
the decreased granularity it caused noticeable audio buffer underruns while it
worked just fine w/ the default granularity (nothing else touched).

Just wanted to report this early on and hope it helps.

So long,
matthias.

PS. Please cc' as I am not subscribed. Thanks a lot.
