> 4. Are there any other settings in the conf file I could try to tweak? One more thing :-) I stumbled over this setting, this made the db (PG 7.4.9) make use of the index rather than doing a sequential scan and it reduced a query from several minutes to some 20 seconds. random_page_cost = 2 (original value was 4). Another thing you ought to do is to to get the four-five most used queries and do an explain analyze in these. Since our website wasn't prepared for this type of statistics I simply did a tcpdump, grep'ed all select's, sorted them and sorted them unique so I could see which queries were used most. regards Claus
