You'll need to provide some details first.
How are you using PostgreSQL?
How many concurrent users?
Mostly updates or small selects or large summary reports?
What hardware do you have?
What configuration changes have you made?
Are you having problems with all queries or only some?
Have you checked the plans for these with EXPLAIN ANALYSE?
Have you made sure your tables are vacuumed and analysed?
That should be a start
