Slow Load Time for Posts

My 2 newest sites are running on the 2010 theme and my newest posts are all taking 5-6 seconds to load. Firebug indicates that its not the plugins. The site is https://www.mydavincikalani.com and the posts are davinci anastasia and Davinci Parker Crib. I’ve uninstalled and re-installed the site and this didn’t solve the issue. Any help would be much appreciated. The problem seems to occur after you’ve visited the post once.
