Sadly Facebook's tools for other sites are some of the slowest things on the web. That they're attached to every post and so can be called 10+ times per page really doesn't help.
Scrolling on TechCrunch with your mouse over the post area is a hilariously pitiful experience.
Actually, since I blocked all Facebook widgets (tracking or otherwise), it has the nice side effect of not loading the comments when I accidentally land on a TechCrunch article.
