Yahoo's front page is 600kb and finishes rendering after about a second. Google is 17kb, and renders in a tenth of that. More Googlification awaits.
Try comparing http://search.yahoo.com/ with http://www.google.com/ , difference isn't as large.
Here's what I get:
curl -s http://www.google.com/ | wc
20 397 14433
curl -s http://search.yahoo.com/ | wc
1 363 12616
