In the order of ease of implementation, it tends to be...

1.  Tweak postgresql.conf
2.  Make sure you ran VACUUM + ANALYZE
3.  Find some expensive queries and try to improve them, which might
    involve changing the queries and/or adding relevant indices
4.  Add RAM to your server
5.  Add disk to your server
6.  Redesign your application's DB schema so that it is more performant
    by design

It is usually a   good idea to  put  a capacitor of a  few microfarads
across the output, as shown.
