One of the highlights for me at the IIUG Conference in April was Advanced DataTools' Fastest DBA contest. Lester Knutsen has advised that the pictures from the event are now available.
What people really want to know of course is how the winners did it.. what performance magic did the winning DBA's work to get their queries so optimized? There are plans to record a webcast this week where the winners will share their secrets. The webcast will be available for playback - look for announcements soon.
The next iteration of the Fastest DBA contest looks interesting too. Expect it to be available online for all-comers to try their hand at extreme optimization.
