OK, a few things you need to look into.
Do you have horrendous bloating in the db. run vacuum verbose on your
db and see what it says. You should probably turn on the autovacuum
daemon either way. If your database has gotten bloated you may need
to vacuum full / reindex to get your space back.
What queries are slow, specifically. you can set the server to log
long running servers in postgresql.conf. Find the longest running
ones and run them by hand with explain analyze at the front, like:
explain analyze select .....
lastly, run
vmstat 10
from the command line while the machine is running slow and see where
effort is going. I'm guessing you'll see a lot of id in there.
