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
whatis running slow, where it should be fast: I/O performance? Query times? Once you have that information, the
communitycan provide much more assistance.
