Not necessarily. Like I said, my laptop currently is about 25 to 30 times faster writing to disk than your server. So, I think something is wrong. Try doing this, run vmstat 1, and while that's running, in another window, do something like: time dd if=/dev/zero of=/mnt/myslowdrive/testfile bs=1000000 count=500 time dd of=/dev/null if=/mnt/myslowdrive/testfile and see what vmstat says while that's running, and how long it takes. I'm guessing something is very wrong and you'll get really low numbers. -- Sent via pgsql-admin mailing list (pgsql-admin@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-admin
