Excellent result ! - Great to see some benchmarking of Postgresql and the competition....and to see it kick ass ! .... but a cautionary note about test "even handedness" - certain current versions of "proprietary databases" will exhaust 512MB RAM with 100 users... I know this because I have performed similar tests of Posgresql + "other unspecified databases" myself. It would be interesting to see memory + swap + disk utilization profiles of the test machine with the various databases. To give the show away a bit, against a certian well known "propriety database" I had to enable "nofsync" to match its performance ( which invalidates a tpc c benchmark I think - no failsafe...) . Not to be a negative Elephant about this, the low memory footprint of Postgresql is a great strength, and should be marketed as such.... ! In a related vein, is it possible that any relevant database parameter settings might be published to help folk get the best out of their Postgresql systems ? ( apologies if they are there and I missed them ) Regards Mark
