I ran iozone auto on my machine and got the maximum of 500K/s throughtput. I saw a report from someone running Interactive Unix on a 50MHz 486 with a Bustek controller getting 4.5M/s. My machine is a 33MHz 486 with 128K of cache, 16Mb of Memory, with an Adaptec 174x controller. I have Julians scsi drivers, and the drive is supposed to be capable of 5M/s. Anyone have a clue to why I am seeing a factor of 10 difference? Where/how does the kernal determine who big of a buffer cache to use? Sincerely, Lars Fredriksen -- Regards, ----------------------------------------------------------------------------
