I'd also like to point out we're putting together some data revolving about software raid, hardware raid, volume management, and filesystem performance on a system donated by HP here: http://wiki.postgresql.org/wiki/HP_ProLiant_DL380_G5_Tuning_Guide Note that it's also a living guide and we've haven't started covering some of the things I just mentioned.

A lot of information is vague and most often then not the answer is "it depends". That's because it does depend. I collect up the best of resources out there and keep track of them at http://wiki.postgresql.org/wiki/Performance_Optimization so if you didn't find that yet there's probably some good ones you missed. Right now I'm working with a few other people to put together a more straightforward single intro guide that should address some of the vagueness you point out here, but that's still a few weeks away from being ready. Monitoring performance isn't really covered in any of this though. Right now the best simple solution out there is probably Nagios with the PostgreSQL plug-in. -- * Greg Smith [EMAIL PROTECTED] http://www.gregsmith.com Baltimore, MD -- Sent via pgsql-performance mailing list (pgsql-performance@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-performance

Depends ;-) You can log queries with an execution time more than N milliseconds via log_min_duration. You can analyse the log with tools like pgfouine. And you can analyse such queries with EXPLAIN ANALYSE. But, i don't know your current problem, that's why my answer are a little bit vague... Andreas -- Really, I'm not out to destroy Microsoft.
