Subject: [Qemu-devel] [PATCH 2/2] audio: Lower default wakeup rate to 100 times / second
Date: Wed, 9 Oct 2013 21:42:38 +0200 [thread overview]
Message-ID: <1381347758-5016-2-git-send-email-hdegoede@redhat.com> (raw)
In-Reply-To: <1381347758-5016-1-git-send-email-hdegoede@redhat.com>
This is more then plenty to keep audio card fifos filles / emptied.
This drops host cpu-load for audio playback inside a linux vm from
13% to 9%.
