Very slow link on homepage

I have some main elements on my home page and the Staff Training and Student Curriculum are taking a really long time to load. I am using New Relic, but I do not see anything that explains why it takes sooooooo long for the page to load.

By the way, I am using Nginx and FastCGI Wordpress setup. This problem persists even if I turn the plugin off. Any ideas what could be causing this? What should I look at? Thanks for your help!

EDIT/UPDATE: I removed all of the php from the page that loads when the linked is clicked and it still takes a long time to load.
