Waiting for static.ak.facebook.com

Peter,
static.ak.facebook.com is the site that loads many assets from Facebook like user avatars or even the Like button itself. If your seeing a long loading time on that, it means your browser is having difficulties loading that content. There's nothing that can be done from your server because your server is not loading that content, your browser is.

I'd recommend:
* Testing from other browsers or computers to see if there's an improvement
* Explore your add-ons in your browser to see if you have any that may be trying to block social network activity
* Ensure you're not behind a firewall (corporate or ISP) that would be blocking social networks

I hope that helps,
Alex
