Date: Sun, 23 Jul 2006 19:08:17 +0000 Mime-Version: 1.0 Content-Type: text/plain; format=flowed X-OriginalArrivalTime: 23 Jul 2006 19:08:17.0294 (UTC) FILETIME=[5AC142E0:01C6AE8B] Sender: linux-kernel-owner@vger.kernel.org X-Mailing-List: linux-kernel@vger.kernel.org The default IO scheduler in 2.6.18 will be CFQ (Complete Fair Queuing) instead of AS (Anticipatory Scheduler) as described here: http://wiki.kernelnewbies.org/Linux_2_6_18. I tried to find (here, at lkml) the discussion about this change with no luck. What is the reason CFQ will be the new default? What advantages it has over AS performance and feature wise? Any links to relevant and recent benchmarks? And if there is a recent discussion about this online, a link would be greatly appreciated.
