A DMA howto I read: "If you have SCSI disks, this is the only configuration you are likely to have, and you do not need to do anything." I ran hdparm while in X with a lot of programs running: $ /sbin/hdparm /dev/sda /dev/sda: readonly = 0 (off) geometry = 13385/255/63, sectors = 215032320, start = 0 $ sudo /sbin/hdparm -Tt /dev/sda /dev/sda: Timing buffer-cache reads: 1988 MB in 2.00 seconds = 994.00 MB/sec Timing buffered disk reads: 198 MB in 3.01 seconds = 65.78 MB/sec I seem to get quit different readings each time I run hdparm. jay -- Shrike-list mailing list Shrike-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/shrike-list
