It's not hard. This is a .gov website and as such isn't plagued with a million external tracking and advertising/marketing scripts. It is also completely static.
Because it is a static document
So what? Most, or at least a lot of, Web documents are pretty much static, but they don't load nearly as fast.
(static, except for the tracking scripts and ads :))
No, they are not. Most of the content on the web is dynamic, based on things like your authentication, geolocation, time, and other things
Ironically, the 5-6 images on the page are really poorly optimized, making the total payload of the page probably 3-4 times as big as it could be.
