I think you're going to need to buy more RAM. 1Gb of RAM means there
is a maximum of 2Mb available per Postgres process before you start
to go into swap

Hi,
I've got very slow insert performance on some
table which has trigger based on complex PL/pgSQL function.
Apparently insert is slow due some slow sql inside that function,
since CPU load is very high and disk usage is low during insert.
I run Red Hat 9
Anthlon 2.6
1GB ram
Fast IDE Disk
Thanks for the advices,
The performance is a bit better now. Unfortunately, the machine does not
allow
to put more than 200 - ~250 users without noticing swap hell.
I have to face the fact that I don't have enough memory
I used the following configuration:
effective_cache_size = 65000
