Swapping - Mailing list pgsql-performance

Hi,

 

I´m trying to tune a linux box with a 12 GB database and 4 GB RAM. First of all I would like to stop the swapping, so the shared_buffers and sort_mem were decreased but even so it started swapping two hours after DBMS started up.

 

I would like to know some suggestions how to discover why is it swapping?

 

I´ve collected the following data from the environment and saved at http://paginas.terra.com.br/educacao/rei/dados.htm

 

1. select version()

2. uname -a

3. cat /proc/cpuinfo

4. cat /proc/meminfo

5. vmstat 5

6. pg_stat_activity

7. postgresql.conf

 

Thanks in advance!
