Message-Id: <20040313232753.63fad84e.sasa@kcore.ath.cx> X-Mailer: Sylpheed version 0.9.7 (GTK+ 1.2.10; i386-pc-linux-gnu) Mime-Version: 1.0 Content-Type: text/plain; charset=US-ASCII Content-Transfer-Encoding: 7bit Sender: linux-kernel-owner@vger.kernel.org X-Mailing-List: linux-kernel@vger.kernel.org Hello, I noticed that 2.6 kernel branch, have some problem with disk read/writes. Today I talked a little with some of my friends, and they say that they don't have that problem, and that 2.6 I/O is acctualy faster than on 2.4 kernel version. However, I did some kind of "tests" on both, 2.4 and 2.6 kernel, with hdparm(-t,-T) and dd(disk writes), and the results is what I expected to be ... 2.4 is faster than 2.6, but, I know that is not the best way to test these kind of things, so I was wondering, is there any "offical" words on this ? Tests ? I supose ther are more people with this kind of problem(i talked to some of them on irc.freenode.net, #kernel and some of them said that have same problem). Kind Regards, S
