I got this bounce message from your account, stefano.nichele@xxxxxxxxxx I'm on gmail too, but don't get a lot of -perform messages into my spam folder. Just in case you've got eliminatecc turned on on the mailing list server, I'm resending it through the mail server without your email address in it. I concur with Merlin you're I/O bound. Adding to his post, what RAID controller are you running, does it have cache, does the cache have battery backup, is the cache set to write back or write through? Also, what do you get for this (need contrib module pgbench installed) pgbench -i -s 100 pgbench -c 50 -n 10000 ? Specifically transactions per second? -- Sent via pgsql-performance mailing list (pgsql-performance@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-performance
