Deck I gave on Optimizing WordPress at WordCamp Philly. These are a combination of my own personal experience and things we automatically do for client accounts at WP Engine. Given the wide range in technical ability of the audience, these slides should provide an overview of subjects for optimization but you'll need to investigate the subjects individually.
