i load data from files using copy method.
Files contain between 2 and 7 millions of rows, spread on 5 tables.

For loading all the data, it takes 40mn, and the same processing takes 17mn with Oracle.
I think that this time can be improved by changing postgresql configuration file.
But which parameters i need to manipulate and with which values ?

Here are the specifications of my system :
V250 architecture sun4u
2xCPU UltraSparc IIIi 1.28 GHz.
8 Go RAM.
