I found this list today via Homo-Adminus, and I think it’s really worth sharing: 84 MySQL performance tips.
Some of these are common sense (eg. index stuff, but don’t index everything), while other are little nuggets of awesome DBA knowledge that only come with experience and expertise.
It’s something you should definitely check out if you work with MySQL.
