Ah, but that's a completely wrong evaluation. The fact that PostgreSQL is available without licensing charges does _not_ make a transactions/dollar ratio break down. After all, the cost of a computer system to run the transactions is likely to be comprised of some combination of software licenses and hardware costs. Even if the software is free, the hardware isn't. If you're doing a high end evaluation, you probably have a million dollars worth of computer hardware. If you're running PostgreSQL, that may mean you can afford to throw some extra RAM on the box, but you still need the million dollar server in order to get hefty TPS counts... -- (reverse (concatenate 'string "moc.liamg" "@" "enworbbc")) http://cbbrowne.com/info/linuxdistributions.html "Let's face it -- ASCII text is a far richer medium than most of us deserve." -- Scott McNealy ---------------------------(end of broadcast)--------------------------- TIP 8: explain analyze is your friend
