Hi ,

     I am experiencing a very bad performance on my production database
lately , all my queries are slowing down. Our application is a webbased
system with lot of selects and updates. I am running "vacuumdb" daily on
all the databases, are the below postgres configuration parameters are
set properly ? can anyone take a look.  Let me know if you need anymore
information.


Postgres Version: 7.4
Operating System: Linux Red Hat 9
Cpus: 2 Hyperthreaded
RAM: 4 gb
Postgres Settings:
max_fsm_pages             | 20000
max_fsm_relations         | 1000
shared_buffers               | 65536
sort_mem                       | 16384
vacuum_mem                | 32768
wal_buffers                    | 64
effective_cache_size      | 393216

Thanks!
Pallav
