Well, SCSI with tagged queueing allows you to send multiple disk requests to the drive and the drive orders them to be optimal. Only the drive knows there the head it at a given moment so it seems good to push such optimizations into the disk drive. -- Bruce Momjian | http://candle.pha.pa.us [EMAIL PROTECTED] | (610) 853-3000 + If your life is a hard drive, | 830 Blythe Avenue + Christ can be your backup. | Drexel Hill, Pennsylvania 19026 ---------------------------(end of broadcast)--------------------------- TIP 6: Have you searched our list archives? http://archives.postgresql.org
