If not, you don't need transactions. - end quote - I don't require transaction because the query aren't complex and update a single tuple (in SELECT transactions are useless) - start quote - You'll find inserts/updates with lots of users is where PostgreSQL works well compared to other systems. - end quote - Uhhmm.. this is interesting... - tutorial links - Thx, now I read it and test an hardware tuned configuration... I read that is not very simple... :O Another question: - why postgres release aren't already configured (hardware tuning)? isn't possible configure it during installation? - why postgres use a new process for every query ? (mySQL, if I'm not wrong, use threads... I think its faster) - why connection time is slower? (compared to mySQL)? - why postgres require analyze? (mySQL, if I'm not wrong, don't require it) Yours answers will be very apreciated! Thx ___________________________________ Nuovo Yahoo!
