I suspect I'm well outside your target demographic, but I'm seeing ~22 whole seconds to onload (according to Firebug) here in Sydney, Australia (as 52 requests comprising 1.6Meg of data.)

That certainly seems excessive for a non-logged-in user on your main landing page.

China and Australia are the worst regions right now in terms of content delivery speed by a factor of 3.

I suspect with a new AWS data center in Australia Cloudfront delivery will become better there soon, and we're looking at Akamai medium term.
