If your session ever suddenly disappears when you're on myspace, this may be why. Here's a favorite bit from the article: 'In other words, on MySpace the occasional glitch might mean the Web site loses track of someone's latest profile update, but it doesn't mean the site has lost track of that person's money. "That's one of the keys to the Web site's performance, knowing that we can accept some loss of data," Benedetto says. So, MySpace has configured SQL Server to extend the time between the "checkpoints" operations it uses to permanently record updates to disk storage—even at the risk of losing anywhere between 2 minutes and 2 hours of data—because this tweak makes the database run faster.'
