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
