Tuning will often double (if not more) the performance.
What are the specs of the box? Memory, CPU, Disk. Are any of these
short? Are you swapping? Pegged CPU? iostat reports heavy disk usage?
What else is running on it?
How often does your data turn over? (Frequency of updates / inserts /
deletes)
I assume you have vacuumed recently? Please attach output of VACUUM
VERBOSE.
Please attach your postgresql.conf file.
Please include the header lines from 'top' output (memory cache / buffer
lines in particular).
