I made other tests today and obtain better results :
I have a program that forks itself as many times as I want (parameter)
and which connects to the base and then executes numerous times the same
fetchs (another parameter) : 3 SELECT via libpq and a call to a PLPGSQL
Function that performs 3 SELECT and 3 UPDATE.
In conclusion, PostGreSQL handles about 65 fetches/sec with 15 processes
(= 15 connections).
It means about 550 queries per second.
The postmaster has the -F -N 256 -B 4096 options
The tests are on a Bi-PIII 660 with 1GB RAM.
Are these results good for you ? Or do you think PG can do much better ?
