I have a few intolerably slow queries and I'm hoping some of you might have some additional query speed-up tricks to share... My limited bag of tricks: * Examine EXPLAIN output to eliminate sequential scans; * Make sure all lookup columns have indices; * Use strictly integer primary/foreign keys; * Avoid using 'IN'; * Use the -F flag; * Regular vacuuming, of course... What works for you folks? Regards, Ed Loehr
