Hi,
after some test i got that my performance problem described in the
message http://archives.postgresql.org/pgsql-admin/2007-01/msg00116.php
is issued by the linux software raid 1 on my discs (yes the silicon
image controller has only fake raid hardware).
I found this old message that seems the same problem like mine.
http://archives.postgresql.org/pgsql-admin/2003-12/msg00219.php
Because the message is quite old I'm wondering if there're some hdparm
settings to enable on the disks that compose the array to have better
performances in fsync.
For now I cannot mount an expensive scsi raid hardware so i need to
have raid software.
Thanks in advance
Best Regards
Federico Campoli
