Postgres Database slow

Hi

We are facing a slowness problem in posgres Database.
Whenver we query a data it is very very slow.It is
running on the IBM ISERIES I5 Server.

HARDWARE: IBM Iseries I5 PPC Server
OS: SUSE LINUX ENTERPRISE SERVER 9.0
POSTGRESSQL: 7.4.2
WEB SERVER: APACHE2

Using the command line also it is taking long time to
query a database.

Any Cluses

Regards
Nirmal
