Hi,

What parameter I should change in order to make postmaster taking CPU as
much as
possible?
Maybe I should ask: how can I make big tables equijoin faster?
I have a serveral tables that contain more 2.5 million records, I need to
equijoin
those tables often.

Thanks!




Jie Liang

There are several good articles on PostgreSQL performance tuning up at
http://techdocs.postgresql.org/

check 'em out.
