I'm working on it!

I'll work on theses issues:

we have space for more ram(we use 2 gigs on possibility of 3 gigs)
iowait is very high 98% --> look like postgresql wait for io access
raid5 -->raid0 if i'm right raid5 use 4 writes(parity,data, etc) for each
write on disk
use more transactions (we have a lot of insert/update without transaction).
cpu look like not running very hard

*php is not running on the same machine
*redhat enterprise 3.0 ES
*the version of postgresql is 7.3.4(using RHDB from redhat)
*pg_autovacuum running at 12 and 24 hour each day

What do you mean by "pg_autovacuum running at 12 and 24 hour each day"?
