jQuery loading thru Google CDN or Amazon CloudFront. Which is better?

Question

After reading thru stackoverflow responses, I am convinced that I have to use a CDN. But which one to use is my concern.

I searched on the Net and couldn't find any info comparing the stats of using Google CDN or Amazon CloudFront.

Please share your experiences regarding the same.

Answer 2

I'd just like to point out that adoption is an issue here, because if a browser has already visited a site using jQuery via a CDN, it could result in a !pre-existing cache of jQuery! even when they're loading your site for the first time! Which is, of course, the best case scenario.

With that in mind, I have to recommend Google's CDN, for the increased likelyhood of previous exposure.

Answer 3

I found this article - CDN performance: Downloading jQuery from Google, Microsoft, and Edgecast CDNs

The author just mention there are some factors need to consider

1. User Location <--> internet speed
2. Widely Used CDN is BETTER <--> Been Cached Already
3. the Reliability of the CDN

So, according to these factors I'll chose the widley used CDN in my region.

Answer 4

It's comparing apples and oranges. Cloudfront doesn't have a public CDN for jQuery, it would be cached from your origin server or bucket. The Google CDN, on the other hand, is a public CDN and is more advantageous since many users would have jQuery cached.
