Many thanks Mark, I will consider fsync=off only to do an initial load, not for a database normal operation. I was just thinking about this hipotetical scenario: a) a restore database operation b) fsync off c) write-back on (IDE) As I could understand, in this sceneraio, it´s normal the IDE drive be faster than the SCSI, ok? Of course, the database is exposed because of the fsync=off, but if you consider only the system performance, then it is true. Isn´t it? Thanks, Reimer
