Good Evening, Before tuning the hardware settings I usually execute an EXPLAIN to see the execution path Postgres uses. A good start to understanding the EXPLAIN functionality is here http://wiki.postgresql.org/wiki/Using_EXPLAIN . Since you're using pgAdmin this is a better tutorial http://www.postgresonline.com/journal/index.php?/archives/27-Reading-PgAdmin-Graphical-Explain-Plans.html. Sometimes using an join instead of a subselect or indexing greatly improves a query even before trying to optimize the default postgres settings.
