I think what he means is that most websites are built with a
tremendous number of referenced images, css, and javascript.  Web devs
use techniques like spriting to reduce the number of includes and
prefixdomains (cache1.exmaple.com, cache2.example.com) to speed up
load times.  .onion sites incur a significant latency hit, so every
additional include is painful, especially when the site doesn't expect
there to be this latency.

The end result is when a user users .onion sites, they can wait for an
extremely long time for the site to "paint" (actually render) because
the browser has to fetch resources that it's blocked painting on
(javascript and css can cause this).  In contrast, it's best to design
an onion site to

a) minimize includes, even at the cost of inflating the page size
b) make good use of caching where possible
c) sprite or better yet base64 images
d) make sure a browser doesn't block painting based on necessary
includes (very tricky)
e) background-load resources and content (or even entire pages) that
the user is likely to want while they are browsing the page
f) potentially, I haven't tried this, using the new prefetch
directives for bleeding-edge browsers

Those are just off the top of my head, I'm sure there's more.  It'd be
great if someone wrote a guide on this.
