Message-ID: MIME-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII Sender: linux-kernel-owner@vger.kernel.org X-Mailing-List: linux-kernel@vger.kernel.org Hi I heard linux does <= 32 page readahead from block devices (scsi/ide/que?). Is there a way to double this? I want to read 256kB chunks from the SCSI drives, as to get the best speed. These numbers are based on some testing and information I've got from Compaq's storage guys. roy -- Roy Sigurd Karlsbakk, MCSE, MCNE, CLS, LCA Computers are like air conditioners.
