Thanks for your help. I'll give you the info you asked as soon as I'll
have it (i have also to install iostat but I don't have enough privilege
to do that).
BTW, why did you said I/O bound ? Which are the parameters that
highlight that ? Sorry for my ignorance....

Hi list,
I would like to ask your help in order to understand if my postgresql server
(ver. 8.2.9) is well configured.
It's a quad-proc system (32 bit) with a 6 disk 1+0 RAID array and 2 separate
disks for the OS and write-ahead logs with 4GB of RAM.
I don't know what is the best info to help me and so I start with some
vmstat information:
vmstat -n 30

-----cpu------

45 0
clearly i/o bound. can you throw an iostat to give some more detailed info?
also,
need o/s version, etc
disk info (speed, raid controller, etc)
my guess is your disk system is underpowered for transaction load you
are giving.
how many tps is the database doing?
