Page load slowed by upfront-dependencies/scripts/

Hi,

I have seen reference to this issue before but have not seen how to resolve it.
My site is showing very slow load time in a pagespeed test with the longest wait attributed to: http://theitpeople.net.au/upfront-dependencies/scripts/0e86e8535c779178e5bea92f8693a9d2?ver=1.1.1 .
I don't know what this means or how to fix the issue and could use some help.
I have granted support access to the site.
