Hi all,

My project ( web application) is using Postgre 8.1 and PHP 4.x (ADO
library to access database). And I would like to increase perfomance, so
I changed configuration follow this:
shared_buffers = 16000(Default = 1000)
wal_buffers = 64(Default = 8)
But this setting is not strong effect. Please show me other way or your
idea to resolve my problem. Thanks a lot.

Best regards,

-Javanesevn.

You need to subscribe to the pgsql-performance list, and once there,
post the queries that are running slow, and the output of running them
with

explain analyze YOUR QUERY GOES HERE

Not explain, explain analyze.

Generally, the more information you give the better.
