Make sure to do several runs to let the CDN cache your file - the first hit will always be slower because it has to go to the source to fetch the file.

I did 5 runs of each and rackspace looks about like your current site (not sure if it is running on cloudfront):

Current site (~70ms): http://www.webpagetest.org/result/110715...5/details/

Rackspace (72ms): http://www.webpagetest.org/result/110715...5/details/
