It is hard to say without more information, but it may be that you
should increase the buffers used by postgres - 1000 is a good starting
point.

My experience suggests that performance is not a 'general' thing
applying to the whole application but in most cases the bad performance
will be one query out of a hundred.

In my applications I wrap my calls to PostgreSQL so I can log the amount
of time each query took (in microseconds).  Then when I have a query
that takes 10mS, I know I can ignore it and concentrate on the one that
takes 20000mS instead.

Regards,
