Ok, is that 20 questions per second (20 in parallel taking 1 second each) or serialized taking 50ms each. Are they simple selects / updates (less than 10 rows in result set, very simple joins) or are they monster 30 table join queries? ---------------------------(end of broadcast)--------------------------- TIP 8: explain analyze is your friend
