Basically, I have a somewhat constant rate of inserts/updates that go into a work queue and then get passed to postgres.
The cpu load is not that high, i.e. plenty of idle cpu. I am running an older version of freebsd and the iostat output is not very detailed.
If you're running a "work queue" architecture, that probably means you only have one thread doing all the updates/inserts? It might be worth going multi-threaded, and issuing inserts and updates through more than one connection. Postgres is designed pretty well to scale performance by the number of simultaneous connections.
