Connecting to 1.gravatar.com
The problem seems to be with the Gravatar service, which supplies an avatar to comments added to a blog post.
WordPress Comments Slow Down Page Speed.
Gravatars Can Slow-Down Your WordPress Blog.
Update: Adding an AdBlock filter for Gravatar fixes this. Simply right click on any Gravatar avatar and select AdBlock Plus: Block image.
Update 2: Not quite. Add a custom filter for http://*.gravatar.com/avatar/* to block all of Gravatar's servers.
s*.wp.com is also causing delays.
