Saturday was a great time. I really enjoyed giving the session on performance tuning and talking to (so many!) developers and DBAs. My best guess were about 160 or more folks were there, which is a great turnout. Anyway, as I promised in the session, below are the slide decks for the session I gave, along with the longer one from OSCON (entitled “Maximum Velocity MySQL”) and the seminar on tag schemas. Cheers!

• Performance Tuning Best Practices
• Maximum Velocity MySQL
  And the two demo SQL queries…
  • selectivity_correlated.sql
  • selectivity_derived.sql
• Tagging and Folksonomy
