-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Mike, I am getting similarly slow performance on my desktop system and am also puzzled. I have set multcount to 16, but am unable to set dma on. I am wondering if there are kernel options for dma that I ought to be selecting so that dma can be activated. I am using 2.4.24 kernel, and my config file has 8 or 10 options concerning dma, most of which I do not understand. What about your power management setting? Is your disk preserving power by spinning down sometimes? Is your dma set? Is your multcount set to its max value?
