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.

Have a look at http://www.powerpostgresql.com/PerfList/ and change your
settings accordingly.

Thanks,

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.

TIP 1: if posting/reading through Usenet, please send an appropriate
subscribe-nomail command to majordomo@postgresql.org so that your
message can get through to the mailing list cleanly

How much RAM do you have, and what is your SHMMAX set to?
