Is there anything I could do to in postgresql.conf file to speed up the time it takes postgres to commit a transaction? 2. Is there anything better than pg_fouine to analyze logs? Thank you, Sincerely, Kasia ^ permalink raw reply [nested|flat] 2+ messages in thread

If you want the traditional guarantee that "commit" means "your data is safely down on persistent storage", there's not much you can do except buy better storage hardware. A disk controller card with battery-backed cache can be a relatively inexpensive solution. Try the pgsql-performance archives for more information than you need on that topic. If you're willing to live with weaker guarantees, consider disabling synchronous_commit. > 2. Is there anything better than pg_fouine to analyze logs? No idea on that one. regards, tom lane ^ permalink raw reply [nested|flat] 2+ messages in thread
