So far I have achieved 79/100.

How I can compress the JS/CSS that is coming from other domains like below ??

http://domain.wufoo.com/scripts/publ...nguage=english could save 62.4KiB (72% reduction).
http://domain.wufoo.com/stylesheets/...index.1028.css could save 27.5KiB (77% reduction).
http://domain.wufoo.com/css/custom/3/theme.css could save 4.2KiB (74% reduction).
http://www.wufoo.com/scripts/embed/form.js could save 4.1KiB (66% reduction).
