Just in case anyone is interested, I benchmarked PG 7 and NT/IIS yesterday. I
ran an .ASP script that inserted 2000 rows using ODBC(one numeric column, one
varchar(50)) into a PG 7.0.2 database running on a Redhat Linux 6.2 computer.
I ran into a few small problems, but they mostly had to do with the script
reloading before finishing. I got roungly 600,000 inserts in a 21 hour period -
that works out to 7.9 inserts per second!! Hardware is as follows:
Machine 1: Machine 2:
========== ==========
P400 P400
128 MB RAM 128 MB RAM
NT 4 RH Linux 6.2
IIS 4 PostgreSQL 7.02
IE 5
Note that although this test is not entirely scientific, it does show what PG7
is capable of.
Enjoy,
Mark

7.9 inserts per second is ok. I reran the test twice though, using IIS/ASP and
eight clients (all doing 200 inserts) with the page automatically reloading
every 60 second, and got 16.8 inserts per second. This is probably due to a
timing issue somewhere, because it significantly exceeds (doubles) the original
script that ran on one client. I ran this script over a 14 hour period and got
roughly 900,000 inserts.
Finally, I wanted to see where the load was. I ran a similar PHP script on the
Linux box that ran PG7, and got a whopping 52.4 inserts per second (10,000
inserts in 3.18 minutes).
So the results would suggest that either IIS/ASP, the ODBC driver, or the
network is the bottleneck. However, we run a switched 100Mbit network, so I am
pretty sure that it isn't the network. My guess is the PSQLODBC driver (
Insight Distribution Systems, version 6.50.00.00).
In any case, my test show one thing - PGSQL itself is NOT the limiting factor,
which was good news for me.
