RE: [PHP-DB] postgresql vs mysql
If we want to go to back to the real world, lets check the results at where most of the world does http://www.tpc.org/tpcc/results/tpcc_perf_results.asp However if $$$ is an issue, don't bother pressing the link :) Sincerely berber Visit http://www.weberdev.com/ Today!!!

i emailed the author (dyck timothy) of this article (server database clash) by eweek he told me that they benchmark DB's according to market share that is why they didnt included PG (not widely used). - Original Message - From: John W.

Real life differs from systems to systems :) It is useful to see how dbms performs, but performance of dbms heavily depends of how users use them. (Isn't MySQL have severe performance penalty with complex query like sub query?) Yes, perhaps you can loan me the money to get Oracle and MSSQL licenses so I can test them out?
