Run: VACUUM (ANALYZE, VERBOSE); More seriously (although make sure you did do that), "performance" is made up of a lot of components. There's no "go faster" switch in postgresql.conf you may have neglected. You'll need to do a bit of investigation first to find out what is running slow, where it should be fast: I/O performance? Query times? Once you have that information, the community can provide much more assistance.
