As part of our ongoing efforts to show how DTrace can be used to tune Java applications, we've set up a booth at JavaOne where you can stop by and take the DTrace Challenge. Put simply, you either leave with a faster app or a free iPod. We're not kidding. If you're in San Francisco for the conference, definitely check this out and chat with DTrace team member Adam Leventhal and DTrace commando Jarod Jenson, who may or may not be hanging from the ceiling this time.
