Using a CDN can vastly improve the load time of a website. I been thinking of using it to host all my external files like CSS, JS, Images, Videos etc. However I was thinking when linking to a CDN, wouldn't the browser have to use additional DNS lookup? So wouldn't this be counter productive? Or is the benefit to host every external files on a CDN out weighs the additional cost of a DNS lookup?

What are your thoughts?
